Photoshop cs5 getting very quirky on me.

I'm running windows 7, and am using PS CS5. It has started developing a few problems that are becoming very troublesome. My system is 64-bit running intelcore i5 2320 3.00 gz with 6gb ram. It's a Dell which is probably the main problem to begin with, but here goes.
The first problem:
It won't open any secondary files on the first try. When it doesn't, I have to scroll through folders, then try to re-open the file. Major headache. On my preferences under performance, "Open GLdraw" is not checked.
The second problem:
It often won't let me make any image adjustments on a file, or on a layer unless I close the program and restart.
Anybody have any of these problems, or know of a fix other than re-installing photoshop?
Thanks!

  • Photoshop CS5 running VERY slow

    Hi,
    My Photoshop CS5 started running very slowly. I followed some suggestions and removed a bunch of programs and services from the start up menu. I also disabled Windows Search Host Protocol as I was getting frequent performance warnings from it while using Photoshop.
    Now Photoshop runs faster, but it takes incredibly long time to save files. The computer goes into hybernation mode waiting for Photoshop to finish saving.
    I imagine this was caused by disabling one of the services in the start up menu or by disabling of Windows Search Host Protocol.
    Does anyone know what programs and services need to be included in the start up menu for efficient working of Photoshop. And whether disabling of Windows Search Host effects the running speed of Photoshop?
    Thank you,
    Margrarita

    Margrarita,
    Disabling Windows services that may be essential to normal functioning of your operating system itself is not something that is recommended.
    First and foremost, we need to review Photoshop's behavior on your computer to be able to advice further.
    Can you go to Help > System Info from Photoshop, copy & paste that data here for us to analyse, thereby give you further suggestions?

  • Photoshop CS5 Issue - Very Annoying

    Hello all,
    I'm having a very weird (and needless to say, very annoying) issue with my Photoshop CS5 Extended. Any knowledge or help would be highly appreciated. FYI - I'm photographer so my primary use is image editing.
    Basically, every time I make a change to a layer (apply a filter or change blending modes), Photoshop does not reflect those changes unless I hit Ctrl+S to save or perform another action (such as selecting a different tool from the tool-set). For example, consider this scenario:
    - I open a PSD file that only contains a background layer.
    - I duplicate the background layer
    - I change the blending mode to "Multiply"
    - Nothing happens to the image (no visual changes even though the image should have gotten darker)
    - Now if I hit Ctrl+S to save the document, the screen is refreshed and now I see the changes.
    I have no idea what might be causing this. I have the latest 12.0.1 patch installed. I have gone through my preferences to see if something needs to be checked but to no avail.
    Any help will be appreciated.
    FYI - I'm running this on Windows 7 - 64-bit
    Thanks
    -ali

    That can be a good workaround, but be aware that some things won't work...  For example, you won't be able to see a preview of your brush hardness using the Alt-right mouse button brush gestures.  And of course zoom won't be smooth, and pans won't flip with inertia (big whoop).  If you have Extended you may not find the 3D features as usable.
    What I'd do if I were you is do some searches for people using your specific video card and see if any of them have found any older drivers that work better.  Then bug nVidia to fix their drivers.
    Alternatively, a really fine video card with huge speed and memory can be had nowadays for a hundred bucks.

  • Photoshop CS5 seems very forgetful of settings and locations..

    is it just me or is anyone else having problems with Photoshop CS5 forgetting things at time. (27" iMac quad i7 core)
    one day it will forget keyboard short cuts, constanstly beeping when I press the space bar to get the move hand, and next day it will work, etc.
    and aols a major one now, forgetting locations. in CS4 and earlier when I opened an image from within a folder, and then saved it as a modified version, it would still save it to within the folder the original image was in.
    now CS5 seems to forget that on occasions and then save the image to the desktop...
    frustrating when using bridge (CS5) as you would doe something in photoshop, switch to bridge (looking within that folder) and suddenly the modified file is not there... and I would search for it...
    just me or anyone else having this problem.
    regards, Sandy

    I haven't seen the behavior you describe with forgetting the save location, but have run into the issue when certain command keys or menu commands don't work intermittently.  I have discovered that much of the time, this can be fixed by selecting a different tool.  At times, for instance, it will not let me type command A or use the menu to select all, but as soon as I switch to a different tool, any tool, it lets me.  I have found this behavior screws up some actions I often use, as well.

  • Photoshop CS5 gets tangible slower after a while

    The subject actually. In half an hour of intensive usage the programm gets slower and finally a simple operation like picking a color with an eyedropper takes seconds. Restarting the programm helps, but it's not very comfortable workflow to restart the PS every 30 mins. I have the PS CS2 installed and it works perfectly as well as other resource-intensive CS5 applications like Illustrator, Flash or InDesign. And yes, have read all official and unofficial advices concerning optimising PS performance and so on. Don't know what system info is relevant to the problem, so here is somewhat:

    Ben, Curt has given you good advice, you need to move your scratch disk to one of the spinners, not the SSD, especially as it is your system disk. Ideally the scratch should be on a separate disk to your system drive regardless, that way Photoshop and the computer itself are not fighting for access, but this is compounded when you're using an SSD.
    SSD's wear out, just like an old LP record or tape, and what wears them is writing to them; each memory cell in the drive has a finite number of writes it will accept before it "dies" and becomes read only. Reading from the drive doesn't affect its life in any way, shape or form, so the ideal configuration for an SSD is for it to be used only for your OS and applications, because once everything is loaded, the vast majority of the activity on the drive will be reads.
    SSD's are fantastically complex, and this is a great article which should give you an introduction to the core technologies and principles involved in their operation.
    Now, after saying that, I've just built a new system with an SSD for my system drive, and I'm going to "recycle" my old systems SSD and install it as the scratch disk for Photoshop; it should speed up the operation of the program itself by orders of magnitude, and it'll be interesting to see how long the old SSD lasts!
    Another piece of advice; if you were to buy a small SSD for Photoshop, do not buy one with a "Sandforce Controller." Once again this is all horribly complex - Google is your friend here - but basically the Controller is where the "magic" happens in an SSD, not in the NAND Flash itself. The fastest drives out there right now all have Sandforce Controllers, but, that speed comes at a price; the drive will basically choke, slow down, sometimes to speeds below that of a mechanical drive, if it has to handle data that cannot be compressed, such as - you guessed it - image files, movies, and music!
    Good luck

  • SDK Photoshop CS5 : Get errors and continue task

    Hello,
    I have a script which applies any functions to contratct, expand, and any other ones...
    I have any thousands images to process. Sometines, there are images which can't be processed.
    I want to continue with the next image when there is a problem but to get the error and to know which image has a problem.
    How can I do that?
    Thanks a lot
    PS : sorry for my bad english...

    In your loop that you process the image files make the actual process a function. Try it and catch any unexpected error and ignore it. Maybe something like this might work
    for (var i = 0; i < fileList.length; i++) {
          try { processImage(fileList[i]); } // try to process images files catch and ignore errors
          catch(e) { }
    Just a guess... You could also log errors (e + ': on line ' + e.line + " processing ffile: " + fileList[i] ) in the catch and after the last files is processed if there were errors list all the files that failed with the associated error messages.

  • Photoshop CS5 - get rid of scanned white background

    Hello
    I scanned a colored logo I did by hand. The scanned white background shows up when I print. How do you get rid of that? I don't want to play with the levels because I like the color of the logo. Do you use the alpha channel and create a mask? If so, what are the steps?
    Thanks in advance.

    select the background with the magic wand tool
    do a feather selection of a few pixels if your selection looks rough
    then do a levels choose the set white point brush and click on what you want to be white
    The levels will only adjust your background to white then.

  • Photoshop CS5 - drag images from web into photoshop issue

    Has anyone had this happen or know a solution? Photoshop CS5 at work does this, but the one I bought for home doesn't... weird
    When I drag an image from the web directly into Photoshop, the program almost freezes, I can select tools, but cant use them, I can get the handles to display with Free Transform, but then cant scale it. I have to actually close the file, then re-open it to continue working.

              The exact same thing happens with my photoshop CS5! very irritating! My boyfriends photoshop CS5 works fine and does not have this problem either! HELP!

  • Photoshop CS5 not working with Lucida Grande Regular font

    On my iMac Intel Core 2 Duo 2.66 GHz, I am running OS 10.6.7.
    When using Photoshop CS5, if I try to use the font, Lucida Grande Regular, it causes an error.
    "Could not use the type tool because of a program error."
    When I try to open an existing file that has type layers that include the font Lucida Grande Regular, Photoshop will not open the file. I have several of these files that I want to use. I can open them on another Macintosh and everything works fine.
    First I get a message window that says, " Some text layers might need to be updated before they can be used for vector based output. Do you want to update these layers now?" I click on update and then get the following message. "Could not complete your request because of a program error."
    I have updated Photoshop CS5 to the latest version, 12.0.4.
    I have run the FontTest.jsx script and it shows an error for Lucida Grande Regular.
    (IOError: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
    - <no additional information available>)
    The other 100+ fonts on my machine did not create errors.
    Since Lucida Grande Regular is an essential font for Mac OS X, I re-installed OS 10.6 in order to have a new version of Lucida Grande Regular. After that re-install I am having the same problems with the font not working in Photoshop.
    It also does not work with Adobe InDesign CS5. The font does work in Microsoft Word.
    The program Font Book verifies Lucida Grande Regular.
    Other fonts including, Lucida Grande Bold, work fine in Photoshop and InDesign.
    What can I do to get Photoshop CS5 to work with Lucida Grande Regular?

    Wow, I'm so glad I found this thread. This problem has been dogging me for years, and it's so sporadic that I've been afraid of breathing the wrong way lest I somehow incur that diabolical Program Error dialog. I'd managed to reach a truce with Photoshop CS5, getting it into a barely working state, and avoiding all updates... until Lion came along today. Then I updated to CS5 12.0.4, and the Program Errors were back again.
    Now I see that the problem does seem to be related to the Lucida Grande font. If there's a layer with that font in it, not only can I not edit that text, but I can't marquee select anything, nor drag any shapes. Deleting caches and massaging fonts are completely ineffectual measures... but if I delete the Lucida layers entirely, we're back in business.
    At least so far.
    Funny to think that of all the innovations I'd like to see Photoshop adopt, the fixing of this one issue is the thing I'd like to see most. I'll be keeping my eye on this thread, and any updates by Mr. Cox.

  • Photoshop CS5 very slow performance, MacBook Pro i7

    Hi, I've noticed some posts on slow screen redraw, but my issue seems to be with specific performance with web based files having many layers and layer groups.
    A sample file is a 27mb psd. It has lot of layers (525), mostly type layers (limited to 3-4 typefaces in the file) and layer groups. If I select a particularly large layer group and try to move it on the canvas, I get the Adobe throbber cursor icon for at least 20 seconds. Even small layer groups bring up the throbber cursor for a few seconds. Overall, things seem much slower than CS4. Not good! And I'm just speaking of basic operations, not hitting intensive tools or major filters yet.
    I've looked at the site below, but not much information except the option to purchase some scripts to 'warm-up' Photoshop. After what I spent on Design Premium, I don't think I should have to purchase third party scripts to warm it up. (I did experiment with the tiles option under performance pref's, but upping that made opening files take 2 minutes, where before opening was achieved in 10-15 seconds.
    http://macperformanceguide.com/index_topics.html#OptimizingPhotoshopCS5
    I have a brand new MacBook Pro i7, 8GB, 7200 internal drive. I installed everything from a fresh install of Snow Leopard. CS4 has never been installed on this Mac.
    Any thoughts?

    if you have 4GB RAM, the system would need about 1-2GB,
    so if you quit all other apps and only run PS, it has 2-3GB RAM left.
    you can set RAM-usage in percentage, in the settings menu of photoshop,
    i set it to 70%, the rest is for osx.
    so lets say PS uses 2GB RAM in your case, the more hires images you open at once and the more layers they have,
    and the bigger they are, the 2GB RAM are gone and PS will use the scratch disc for the mentioned images you opened at once, which is also configured in the settings menu. usage of a scratch disc (PS writes data to the scratch disc permanently) will slow down overall performance, it may lagg and everything is slower than before (in my experience). best for scratch disc usage is a separate, fast, internal disc, as huge as possible (50-250GB discsize and empty, no files on it, so that PS can write continously, in order to avoid disc-fragmentation, which would slow down the writing process additionally)
    thats the reason i would add 8GB RAM.
    RAM is very important for photoshop CS5.
    (also processor clock speed and number of cores - in the moment 2 cores are enough
    as CS5 isnt optimized yet for more than 4 or 6 cores. more to come soon, i hope...
    in my case, i added 24GB RAM, cause i want to avoid usage of a scratch disc at all. this is a huge gain of performance for myself.
    i never liked my old scratch disc, as working was terrible slow with it. i also had only 4GB RAM in my last mac, and working was no fun
    i work on large format files, 50-100cm at 300dpi and lots of layers, each layer has to be seen like an image itself, so each layer rises RAM consumption.
    its a pitty that i never saw adobe delivering some kind of performance guide for photoshop, how to improve performance for professional users, like posting that guide on their main photoshop site, i had to digg for these informations for a long period of time and found it in the end at diglloyd´s comprehensive site. i wonder why adobe makes a secret about photoshop performance, a lot of my friends at work mentioned formerly, that they have had huge lag issues and dont know where to begin solving these problems, which are solvable for sure.... (new hardware, proper settings and so on)
    you can read detailed instructions, on how to speed up things in PS here: (where i took it for myself)

  • Photoshop CS5 Very Slow Liquify

    I've noticed that in Photoshop CS5, Liquify just works terribly slowly. When I click and drag to distort an image, the image gets distorted sometimes even 10 seconds after I've lifted my hand. Sometimes I have to wait 30-40 seconds for the distortions to happen before I can regain control of Photoshop.
    Also, panning is a bit more choppy than in CS4, which annoys me a lot, as it was the case with CS4 compared to CS3, etc... I predict that panning in CS7 will look like a slideshow.
    And another thing, when you Flick-Pan, and release the mouse, the canvas flies across the screen, and during that flying animation, in CS4, you could still zoom in and out with the keyboard. In CS5, you have to wait until the canvas has slowed down to a stop to be able to zoom. This is also a strange feature.
    Adobe said CS5 will have performance improvements, and I can see filters, adjustments and brushes perform a tiny bit better, but basic things like panning, zooming and liquify got MUCH worse and less responsive, and this is not worth the tradeoff for me, since I use these features very frequently, many times a second.
    I use a Wacom Bamboo Fun tablet most of the time, and I noticed that Liquify is much faster (although still too slow for me to use it) when I use my trackpad instead of the pen.
    I'm using the Photoshop CS5 trial now, and I have Photoshop CS3 and CS4 both installed on the same computer, so I can tell that CS3 ran much faster, CS4 was a bit slower and CS5 is a LOT slower. I'm using a late 2008 15 inch Unibody MacBook Pro with 9600M / 9400M graphics, 4GB RAM and 2.53 GHz CPU, and speed gets a bit better when using the 9600M.
    Here are my questions:
    Has anyone else had any of these problems, especially Liquify?
    Has anyone else used CS5 and noticed that Liquify runs just fine?
    Does anyone have any suggestions of what I could try to cure any of these problems?
    Is it possible that this is the way Photoshop CS5 should run on my computer, due to my hardware limitations and bloated software?

    How long is it going to take to fix this liquify problem?? Come one guys I need it to work now and better than in CS4 not worse!!! Otherwise why did I spend almost 1K to upgrade???
    Looking into the problem isn't enough!!! I need a solution since I use the liquify tool for almost 99.9% of my images (fashion/beauty photography retouching).
    Is there a temporary fix??? using the CS4 liquify plugin into the CS5 software?????
    do  a google search on slow liquify and see what comes up..... still pretty nice and insecure requests for the reason why it is so slow because users think it is their machine (computer) but if I don't get an answer and fi very soon (couple of days at the most) this nice and insecurity will vanish for a HUGE ADOBE *** kicking campaign !!! Since photoshop is known for their arrogantly slow updates for their software and waits till the next big update to correct things....I am not going to wait 18 months for you guys to fix the liquify problem!!!
    SO GET TO IT NOW!!!!! So I can do my work and make enough money to keep spending on adobe upgrades!
    And as a side note...didn't you "wizzards" have enough time to discover this BIG problem beforehand?? Or were you to busy fighting with Apple about your huge Flash problem??

  • Photoshop CS5.5 Layers partially disappear. Cannot get them back.

    Adobe CS5.5 Photoshop running on Mac OS X.
    This is a brand new installation, just purchased and installed last week, and this is the first graphic heavy task I have attempted using Photoshop CS5.5. I was working in a document (photo-manipulation) and eveyrthing was going very, very smoothly. I was using mostly Masks. The issue ocurred immediately after I tried to apply a Hue/Saturation effect to the topmost layer. All the layers experienced partial disappearing. Even though they appear whole in the layers tab, on the stage huge parts are missing.
    See this screenshot:
    I tried to undo the Hue/Saturation, close Photoshop completely and reopen, and double checking the settings on each layer. I was saving as I went along but even closing without saving and re-opening the file did not help much. Most of the disppeared portions have returned, but there are still "chunks", sort to speak, that are "missing". I have spent about four hours on this piece so far, and I really do not want to have to go back and re-do the "missing" parts (that are not really missing just not showing up). And the layer with the knight is not supposed to be black, Photoshop did that all on its own. O.o
    Has anyone else experienced this? Is there a way to get all of each layer back visible? I have used Photoshop CS2 and I have Photoshop CS4 on my other computer, but I have never had this happen in any of the earlier versions. And this being the first time I used Photoshop CS5.5 for more than just saving screenshots... Yeah. Any ideas?
    ~Jacquelyn

    On your recommendation, I tried turning off the OpenGL and restarted Photoshop. I also checked the blend settings. No change. I am beginning to think that perhaps the missing "chunks" on the various layers were somehow deleted. Though I did not select nor delete anything. It is very curious. I wish I knew what happened (or what I did by accident) so I can prevent this type of thing from happening in the future.
    Anyway, I spent a few extra hours re-doing the parts that were "missing" and now the piece is finished. http://fav.me/d49b0sz

  • Suddenly Getting Green prints in Photoshop CS5 and Lightroom 2.6

    Photoshop CS5 12.0.1 x32, and Lightroom 2.6
    Windows XP SP 3
    Printer: Epson R1900, Software 6.61 (current)
    HP LJ2475W Monitor
    I have been running and printing from Photoshop since 5.0. I have had CS5 several months, and probably printed 20 or so pictures (matte, gloss, lustre, from 5x7 to A3). Last weekend, I just wanted to print a quick 5x7 of my wife at my daughter's wedding. The print looks fine in Photoshop, and in the Photoshop print preview, but when it gets to the Epson print preview, the colors are distorted and very green. This is the way it prints also.  I get the same results from multiple pictures includeing those I have printed with no issue before, and in Lightroom 2.6. The only thing I can print successfully is a PDF I constructed a few years back in Photoshop with a bar of each color and a black-to-white gradient (I use this to "exercise" the inks when I don't have something to print during a week).
    I worked with the technician from Epson last night, and it is not a problem with the printer. Using the WIndows Picture and Fax viewer, I was able to print the same picture (and several others) with no issues what so ever, and with all the correct colors. When printing, I used the same ICC file I was using in Photoshop.
    I have rebooted multiple times, I have downloaded the latest printer driver from Epson, along with the lastest ICC files that they supply, all with no results. Again, it prints fine outside of Photoshop CS5 (Lightroom 2.6 has the same issue), but has corrupted colors within Photoshop.. I have no clue what to adjust or change to get it to print correctly again.
    I have downloaded and installed the lateset Adobe patches when prompted to do so, as I do with the Micrsoft patches. Other than that, I haven't had any recent downloads. It was working correctly 2 weeks ago, the last time I printed (this is used almost exclusively for Photoshop and Proshow Producer).
    Thanks in advance for any suggestions. I don't want to have to be limited to other programs to print my photos.

    I think I'm seeing a trend of double (or multiple) color transformations here...
    SOMETHING, somewhere, is causing the inability to turn off ALL color management outside of Photoshop, so that one cannot use the "Photoshop Manages Colors" setting without getting multiple transformations.
    Has Windows itself perhaps added a color management stage somewhere in the mix?
    Has something changed that causes the Color Management: Off setting in the printer drivers to be ineffective, or more complex than just "on" or "off"?
    What do we know so far?
    With CS5, many people using Epson printers cannot get reasonable print colors unless they use the Printer Manages Colors setting in Photoshop.  I don't know what they're choosing in the printer drivers because I don't have an Epson.
    I personally have seen evidence of double profiling (magenta looking print) with my HP printer when Photoshop is set to Printer Manages Colors.  This is kind of the opposite problem from what people are reporting about Epsons.
    The ICM Method setting in my HP drivers has an entry entitled ICM Handled by Host System, which is SEPARATE from ICM Disabled.
    Given the above, a person could be forgiven for thinking there are more combinatorial choices than just these two:
    Photoshop Manages Colors and "ICM disabled in the printer / drivers"
    Printer Manages Colors and "ICM handled by the printer / drivers"
    What does the Epson printer driver color management selection look like?

  • I don't have a Camera Raw option in Photoshop CS5. Where do I get the correct plug in??

    I have been trying to download plugins for the Camera Raw option for Photoshop CS5.  It is not working....I get a message that 6.4 is not found and 6.5 not compatible.  Where can I get the correct download for Windows 7?  I am very frustrated.
    Thank you!

    Here is he download page.  http://www.adobe.com/support/downloads/product.jsp?product=106&platform=Windows
    For CS5 you can download 6.7  Do not need the prior ones as they are cumulative.

  • Am useing a PC. Have Photoshop CS5, suddenly cannot move Raw files from bridge (or anywhere else) into photoshop. Jpeg move into photoshop ok, did get error message 1 what do I do to correct this                om bridge (or anywhere else for that matter)

    Useing a PC
    Have Photoshop CS5
    Suddenly cannot move Raw Files from Bridge (or anywhere else) into photoshop.
    I Can move Jpegs into ps the only issue is with Raw files
    I did get error1 message but as do not know what that means its no help
    any suggestions?

    Sorry for the late reply. My email firewall has become a little over zealous & sent a lot of my emails straight to my junk email folder, so I have only just now discovered your reply in my junk mail folder.
    The only "don't open files exceeding xxx megabytes" instruction I can find in my Prefs, is in the Bridge Prefs for Thumbnails, & mine is set at 1000mb. The biggest files I handle are bigger than 200mb so I should be able to open a few, not just one.
    However, this doesn't explain why I can open a psd format file of 180mb, close it, but then can't open a RAW format file of only 26mb immediately after.
    I can open the RAW file only if I restart my computer - very annoying!
    However, thanks for the advice about the video card & memory.
    So, I'm still stuck as to what the issue is.
