When working on word file or watching a film on safari my screen starts flickering and then disappears

Dear All,
When working on word file or watching a film on safari my screen starts flickering and then disappears? Is it dangereus? What does it mean?
Thanks

Go to another Optometrist and get a second opinion or see an Ophthalmologist.
Ciao.

  • Can't open documents - File select screen just flashes and then disappears

    In Adobe Creative Suite 3 Design Standard - When I open Photoshop, Illustrator, etc. and then try to open a document from one of these programs, the screen where you would select the file to open just flashes and then disappears. This locks me out of the program because it is waiting for a response from me - I can't even exit the program. I have to go to the Task List and close the program from there. This is a new issue - Have had Creative Suite for a while. Does not happen in Word, Excel, etc. I have already tried removing and reinstalling the software - No change. I have minimized all other windows - Still cannot access the file selection screen.

    If you have an LCD monitor, make sure it is running at its maximum resolution. After the dialog disappears, try pressing Alt + Spacebar, then M and see if you can find it on the edge of the screen and move it in by pressing arrow keys, press one a few times, then the opposite to bring it back if it didn't show up.

    Generally when creating a Word file from either a Mac or Win7 pc and opening it on two different machines (either one first) it always prompts that the file is open and will be opened as read only.
    However opening a CSS file does not prompt that it is already open on or from any machine which is causing code edits to be lost.
    What we found from out testing:
    - The file can be saved from one user to the server and WILL NOT PROMPT on other machines until the saving machine has the Dreamweaver program closed completely
    - The file can be closed and  Dreamweaver minimised to the launch bar but it still will not register on other machines that it has been changed.
    - Also, until the  Dreamweaver program is closed on the machines, it will continue to open it's saved version of the file. 
    Example Scenario:
    - User 1 opens test.css (which is 2000 lines) and adds some code to the end of the file to bring it up to 2500 lines
    - Meanwhile User 2 opens test.css as well (opens as 2000 lines as User 1’s edits have not yet been saved) and adds in code to bring it to 2300 lines
    - User 1 saves his file and closes it - but  Dreamweaver is still open.
    - User 2 also saves his file and leaves  Dreamweaver  open.
    - The server will report the size and last edit of the file the same as User 2 as he was the last person to save it (and if you open from the Win7 Machine it will show as User 2’s 2300 line version)
    - If User 1 then open's the file again (from either the 'recent' in Dreamweaver OR clicking on the file directly in Finder...which version opens.... The version that User 1 saved! Not the true version on the server, but the version that User 1 edited and saved with 2500 lines in it.
    - Same for User 2, he will open 'his' version with 2300 lines in.
    Other information:
    - Files are opened directly from the server
    - Sometimes the users will save incrementally and re-open
    - Most of the time users will save incrementally and keep the files open
    - The users will never not save incrementally and just save when closing the file once finished
    - The users are usually working on the files all day
    - It is always the bottom lines of code that are lost. It could be a case of the two versions being mixed up and cutting off the newly added lines based on the line count (possibly).
    It is as if Dreamweaver is holding a cache of the version locally and then only properly looking back to the server when it has been completely closed. It is very difficult to see how the server is causing such an impact on these files, there are very few logs which are giving any indication to the root cause of the problems.
    Anyone know if this is a known issue?
    Is there a way that there can be a featured implemented on the server that doesn't allow another user to open a file if it is already open on another machine?
    Thanks

    Your server file handling has nothing, and really nothing to do with Adobe software. If files don't get locked for (over-)writing and/or lose connection to the program opening them, then your server is misconfigured. It's as plain and simple and that. Anything from "known file types"/ file associations not being set correctly, MIME types being botched, crooked user privileges and file permissions, missing Mac server extensions, delayed file writing on the server, generic network timeout issues and what have you. Either way, you have written a longwinded post with no real value since you haven't bothered to provide any proper technical info, most notably about the alleged server. Either way, the only way you can "fix" it is by straightening out your server and network configuration, not some magic switch in Adobe's software.

  • Very slow responce when working with Office file on DFS-Share

    Very slow responce when working with Office file on DFS-Share
    We have implemented the following configuration
    Domain level Windows 2000. Two member servers with Windows Server 2008 R2, sharing the same DFS namespace with, at the moment, one folder target called Home.
    Users complaining that the access to different MS Office files is very slow. Even creating a new MS Word document using right click context menu takes up to 4 minutes to open. Saving, for example, one singe Excel sheet takes also few minutes.
    Tested with both, MS Office 2007 and MS Office 2010. Makes no difference. When using Office 2010 you can see the message like contacting:
    \\DomainName\Root\Home\UserName. Other files like TXT, JPG or PDF are not affected.
     What makes the thing really weird is the fact, that the behavior described above can absolutely change after client machine being rebooted, suddenly everything becomes very fast and this condition can revert back again just after the next
    reboot.
    Considerations until now:
    1. This has nothing to do with the file size. Even tiny files are affected.
    2. AD Sites are configured correctly and the client workstations see themselves in the correct sites.
    3. This is not an Office issue. If I map my folder target not as DFS, but directly as shared network drive
    \\ServerName\Root\Home\UserName , everything functions as expected
    What makes me suspicious: when using f.e. TCPView to monitor connections, I can see, that each time I make any operation on an office file, there will be a connection established to one of the domain controllers, sometimes to remote ones,
    located in other countries. But on the other side, even if the connection is established to the nearest DC, operations are still very very slow!
    Just forget to say. All clients are Windows 7
    Thanks to all who respond.

    Dear all,
    sorry for the delayed reply. The problem has been solved now and since September 19<sup>th</sup>. everything is functioning as expected.
    What was done:
    Deleted replication targets excepting the initial ones
    Carefully recreated folder targets
    Deleted and recreated  replication groups
    Disabled SNP features on both namespace servers
    Created EnableTCPA registry entry
    Checked that the following Updates are installed

  • How to maintain original lines when converting a word file in a PDF

    Unfortunately the table lines often change when converting a word file in a PDF, e.g. dotted/broken lines into straight lines or different kinds of broken lines. How can I maintain the original lines when converting the documents?
    Many thanks in advance for your advice.

    Hello,
    Ok, this is the background.
    I’m a publisher. Any document to end user will go as pdf. And off course it preserves the word appearance. We ship our manuals only in pdf.  At this point my end users have to copy the “CODES” into his editor to run the product.  So when doing it, the “Codes” copied from pdf to his editor loses its format.  Editor need not be the actual one; you can also test in a notepad.
    P.S: You can find the difference by copying the code from word to notepad and pdf to notepad
    Hope you now understood the purpose what I’m looking at for.

    Sorry, no further idea what can cause this.
    Is the shortcuts file truely saved to disk? You can find in the user path, where the preferences and presets are stored for PS. Or if you go to the dialog again where you change shortcuts, is it reverted there too?

  • Bought Garageband for iPad1 and it worked like a dream. Then I upgraded my system to 4.3 and now Garageband doesn't work. How come? When I try to start it just flickers and then goes back to show the symbol for the app.

    Bought Garageband for iPad1 and it worked like a dream. Then I upgraded my system to 4.3.5 and now Garageband doesn't work. How come? When I try to start it just flickers and then goes back to show the symbol for the app.

    I understood what you were saying. You did type 4.3.5 in your post. Several other things to try.
    Close all open apps like I described above. Just tap the home button first so that you will be able to access all of your apps. Close every single one and then restart again.
    You can also delete the app and download it again. As long as you use the same Apple ID and password there is no charge to download it again. Tap and hold down on the GarageBand app icon until it wiggles. Then tap the X to delete it. Download it again.
    Reset the iPad. Hold down on the sleep and home buttons at the same time until the Apple logo appears on the screen. It takes about 10-15 seconds. Ignore the red slider shut off bar. When the Apple logo appears you can let go of the buttons and the iPad will reboot.
    The final thing to try is to download another app - any free app. Sometimes that seems to reset something on the iPad. You can always delete the free app if you don't want it.

    Can you open Adobe Reader by itself?  If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].

  • I think the DVD player reader on my Mac is going bad. Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive?

    I think the DVD player reader on my Mac is going bad. Until I get it fixed Is there a way to copy the files off of an Apple Install DVD onto an external drive and then do theinstall from the external drive? It's ILife 11 if that makes a difference. Finder won't let me see the files to copy. I know - dumb question.
    Thanks.

    Adding an SSD is not a simple endeavour like adding additional memory or adding another hard drive to a Mac Pro. That's probably why the option is only offered as an option at the time of purchase. Even if your Apple store was willing to install the necessary parts you will probably be paying for 1-2 hours of labor plus the cost of purchasing the necessary service parts (SSD, bracket, cables, etc) which I suspect will make the upgrade cost much higher than what it costs to add the SSD option when purchasing a new system.
    I use my system for business and need it to work reliably.  Even though I'm fairly handy with tools I would not be willing to risk damaging my system and voiding my warranty by opening my system and removing the logic board and several other parts in order to squeeze in an SSD option and attach the appropriate cables and brackets. I'm also not prepared to deal with the hassles of explaining why my system has unauthorized parts installed in the event I experience issues and need to make use of my Apple warranty. My time is valuable, so I would probably investigate external storage options, or if I needed the speed of an SSD, I would consider selling my existing system and then purchase a new system configured with an SSD.
    If you haven't already done so I suggest doing a search on 'iMac SSD installation' to see what's involved. It might help you understand why the SSD option is not offered post purchase.

    Hello BassoonPlayer,
    Since you are using one of the the school's Macbooks, it is quite possible that the time and date are not properly set on the computer that you are using.  FaceTime will not work if you do not have the proper time zone set up for the location that you are in.  This past week, there were a two other Macbook users I've helped by simply telling them to set the Date/Time properly.  By the way, you described your problem very well, which makes it easier for us to help you.  Hope this solves your problem -- if not, post back and I can suggest other remedies.
