Why does Grab give me an all-white result?

After rebooting, Grab works fine, but within a couple of hours it starts giving me an all-white result. It grabs the proper size image, but the image is entirely white. This is true whether I grab a selection, a window, timed, untimed, all variations on grabbing are entirely white.
No messages appear in the console indicating anything is wrong. Quitting Grab and relaunching it doesn't help. Rebooting the computer fixes the problem temporarily.
Mac Pro with OS X 10.6.8, Grab version 1.5 (101), all software updates applied, all permissions repaired.

I think you are absolutely correct about Trusteer. My bank uses it too, although I use Firefox rather than Safari.
I tried this experiment:
* I tested Grab, it was working fine.
* Logged in to my online banking, Grab now fails, gives me all white.
* Logged out, Grab still is all white.
* Closed the Firefox tab in which I had the the online banking, Grab now works fine!
Just to be sure, I repeated the above sequence again, got the same results.
Further testing suggests that all I have to do to break Grab is to have a tab open in which Trusteer is active, it doesn't matter whether I've logged in yet, simply being at a Trusteer-protected login screen breaks Grab.
Looks like problem solved, thanks!

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?

Why does my iphone 3gs screen go white after it goes "to sleep" for the first time after turning it on?
The screen isn't broken because it works after i turn the device off and back on, but after it goes black once, it's only white again.
But it takes the touches although it's only white, because I can answer my phone when I slide my finger on the bottom of the screen, eventhough there in not the button to see.
This is so weird. I have already done everything I can think of that might help. But I cannot think of anything that might be causing it, because nothing has happened to the device.

Let me know if I should start a new discussion instead of opening a new topic here.
My wife's iPhone is the same vintage as mine 3Gs, but has never had the battery problem. Its affliction instead is that it cannot detect WiFi networks unless it is quite close to the source. Often, when my iPhone not only detects but shows a maximum cells connection with a network, hers cannot detect the network at all. In contrast, her iPhone seems to detect ourcellular carrier just as well as mine does.
Is there any help for this affliction?

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them.
Notice how in the photo, I can't identify which MS office document I would like to switch too. Perhaps since the Dashboard and Desktop windows are at the top of my screen now Apple doesn't let you have all the applications take up the full screen and be sized individually so that you can have a better idea on what to pick.
I like the idea of grouping to an extent... If you have a bunch of random things it was hard for me to decifer between what was safari, chrome, or word. But now that they grouped them like this, if you have multiple pages of one program running, you can't switch between those pages easily like before.

If I wanted to open any of my Applework documents I had to open them one at a time and resave them with pages. This could take weeks.I have 1000s of apple work documents.
You don't have to open and re-save every AppleWorks document you have right now. Just wait till you need one, then do it. The documents aren't going anywhere.
Am I dealing with Microsoft? This was a BIG surprise to me that Apple would release an OS without testing all programs.
Frankly, it is not Apple's responsibility to ensure compatibiltiy with every piece of software available for OS X. That is the responsibility of the software vendor. Lion has been available to developers for several months before it's release, so Microtek had plenty of time to update their software. Yet they did not. How is that Apple's fault? I think Apple was very generous to give you a refund for Lion.
I'm not trying to belittle your frustration but I do think your ire is misplaced.

When adjusting the audio volume in a selected region, why does it give me a curved line instead of straight and why cant I change it like i can with a fade in our out?

When adjusting the audio volume in a selected region, why does it give me a curved line as a transition instead of straight, and why cant I change the fade shape like i can with a fade in our out? When I slide thet volume all the way down it makes a very abrupt down curve. It's audibly noticdible.
Thank you.

Use the range selection tool and select the portion of the clip you want to change the volume on. Drag the volume line down and FCP will create keyframes which you can adjust as you want to get a fade shape.

Something is/was modifying my DNS preferences to 8.8.8.8 It seems to be pointed correctly now (at my local LAN DNS server), but why was it pointed at 8.8.8.8 before? I never want it pointed to 8.8.8.8

You've hit the nail on the head Ben. For point to point communications, the IP addresses should be fixed, therefore there is no need for DNS. If a DNS is configured, the NIC (Network Interface Card) drivers will try to contact it.
In my test system, I need DNS for the test computer, but I am communicating with a dedicated Spectrum Analyzer over TCP/IP. So I added a second NIC. The main NIC is configured for DNS and all that jazz. The second NIC (plugged into PCI slot) is configured with a hard coded address, no DNS, no Gateway, nothing else. I connect that NIC to the spectrum analyzer using a crossover cable. The analyzer is configured with a hard coded address also. Now my computer can get on our company network, and the spectrum analyzer is isolated from the network, so it can't catch any viruses, etc., and it still talks to the computer. When using a configuration such as this, it is best to use a dedicated address for the 2nd NIC and spectrum analyzer in the range of 192.168.100.0 to 254

You might be able to re-enable it via this page : http://appleid.apple.com, then 'reset your password'
You might then need to log out of your account on any iOS devices that you have by tapping on your id in Settings > iTunes & App Store (Settings > Store on iOS 5 and below) and then log back in so as to 'refresh' the account on them
If that doesn't fix it then you might need to contact iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page

Why does my Ipod not synchronize all playlists? Some get synchronized, others don't. Yet there is enough space available.

Why does my Ipod not synchronize all playlists? Some get synchronized, others don't. Yet there is enough available space.

The S.I. prefix Giga is used to mean both 1000x1000x1000 and 1024x1024x1024. Computer software typically uses the second version, but using the first number makes the same number of bytes appear bigger when expressed as Gb, so is favoured by hard drive manufactures.
80Gb10 = 74.3Gb2
It's a bit like specifying a quantity in gallons without saying whether they are US or Imperial gallons - everybody gets the same volume but one number will be bigger than the other. I could offer you a tank with 10 Imperial gallons of fuel in it - but if I tell you it's 12 US gallons it sounds like you're getting more for your money.
Once the total size of your library exceeds the capacity of your device all you need to do is create some size limited playlists to determine what goes on the device. Don't sync all movies, sync one or two that you plan to watch soon. Likewise with TV Shows. Limit podcasts to unplayed episodes and finally create a music subset. What worked for me for some time was a smart playlist called Steve's Tunes defined as Playlist is Music and Playlist is not Exclude where Exclude was regular playlist that I would manually add to until Steve's Tunes was small enough to fit. These days I run an iPhone and have a number of smart playlists with ? Gb of most played, ? Gb of highly rated, ? Gb of recently added, ? Gb of essentials, ? Gb of unplayed etc. Each time I sync I get slightly updated selection without having to put any extra effort in.

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Why does 3Dmark05 give me this error?

This is a version I got off Limewire and its not full retail. Its only a demo. Got this error:
IDirect #DDevice9:Present failed:Device lost(D3DERR_Divice Lost)
I have the latest drivers off the Nvidia website. What gives? Never used 3d05 before, but I was just testing my new ASUS hybrid card with various benchmarks to make sure things seem to be running right. I do get a posted score in 3dmark05, even though it kicks me out and zaps my screen temporarily to 800X600. 3dmark05, after clicking the ok buttun after the error message posts my score 3,106 which seems about right seeing that I have a slower system.
So far I have only benched this card, havent played any games for more then ten minutes. graphics seem better.Im not seeing the improvements in Far Cry that I though I would get from a 6800GT on full settings. I know this is a DDR128, but I just though things would be a smoother. Clarity is much better then the 9800pro and this card runs suppringly cool that 6600GT I tested was dangerously hot and I didnt want anything that hot in my case.
I dont think there is anything wrong with the card. I tested a 6600GT the other week and the this 6800GT hybrid did get me from 43K to 46K on Aquamark3. My 9800pro was at 41K with a slight overclock.....maybe I try some Farcrytests to see if that shows anything...
BTW I just was going to tell you have the latest drivers and was going to post the version, because after I got the card up and running I downloaded the latest from Nvidia. Why does my Display Adapter when I click on properties say "7/9/2004" version "6.2.1.1"?....Now when I ran the driver update, it said it was updating the drivers and the drivers name they were version 9/13/05?

Quote
>It sounds like the version you got may be damaged. I would try getting the download directly from futuremark. The link >to download it is http://www.futuremark.com/download/?3dmark05.shtmlQuote
I tried it with another version of 3Dmark05 and got the same error. I also noticed it does it during the CPU test where it tries to make the CPU think its a GPU. I found this:
http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/directx9_c/directx/graphics/programmingguide/gettingstarted/devices/lostdevices.asp
I also checked around the net. Seems like there are two reasons for this "lost" error. A resident program pissing 3dmark05 or a voltage issue....I havent had any problems with my system and only have then with 3dmark05. This is with a new version of 3dmark05 and newest drivers installed after Driver Cleaner. SO I still dont know whats up....Again it only does it durring the CPU test for 3Dmark05 and in particular always errors out right when the monster is emerging from the water During the zepplin test.

I was able to play >FarCry on my machine will ultra settings with my 9800 (but no anti-aliasing or ansiotropic filtering). And only going from >41k to 46k with aquamark also seems low.

If not I would >remove both the NVidia drivers and get the cleaner and clean both ATI and NVidia drivers off of the system and >reinstall your NVidia drivers.Quote
In my previous post I noted that I was only using the ASUS drivers dated 4/05. Well I went back and used Driver Cleaner then tested. The scores were about the same, but gameplay and visuals were much smoother as I would expect from a card like this. I though that was odd given I had pretty much the same scores(meaning Aquamark stayed the same and 3dmark went up about 300 points). I then went back to Nvidias site and got the newest drivers and they loaded right this time
Aquamark: increased 1,000 overal to a solid 47,000-47,500 (I was getting 41K with 9800pro,XTbios OC)
3dmark03: 9608 (from 9137)
3dmark05: same score no changes (as noted above still errors out at CPU test)
Thanks for the input I am VERY happy to be running solid 47000-47500 Aquamarks where as before I was runnign 45500-46000 with driver issues. I not as familiar with 3dmark scores and how the differences pan out when playing games. But you mentioned that My scored seemed low. Is this 47,500 more like what you thought? Also remember the card that I have is a 16,6 6800 GT but has 1ddr128. In this review this guy only gets for 3Dmark03 10,290(vs my 9,608) but he has a 64 bit system. In another review using 3Dmark05 the guy gets 3,838 vs my 4,060 Here the card with some scores:
http://www.digit-life.com/articles2/gffx/nv40-11.html
http://www.ap0calypse.com/showthread.php?t=1287
Things of note:
1.) Graphics seemed less chopy by just using driver cleaner, but scored stayed about the same.
2.) After gettting the latest drivers too. Aquamark showed a significant change, yet 3d05 stay the same
3.) Question Driver Cleaner said to "empty the recycle bin" while in safe mode. I couldnt do this. How do I do that?
4.) All this with the 1.3 Far Cry patch makes the game much nicer. I can do Full Blast settings, but there is some screen rippple every 15 seconds or so. Not to bad, But not flawlwss like a 64 bit system.

Why does my Mac stay on the white screen when I turn it on?

Why does my Mac stay on white screen when I turn it on?

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 3
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 4
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 5
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 6
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 7
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 8
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 9
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 10
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Why does status bar say that all items are not loaded?

When I have the status bar displayed at the bottom of my page, and I load a page, it usually says 4 of 5 item complete, or 6 of 7, or even one time, 92 of 93. What does this mean exactly? And why does it never say all items are completed? Is anything wrong with the browser, or is this just code for something?
Thanks,
Jeff

These days web pages have many little extras, not just images, that have to be downloaded when we click on a link to a page. Sometimes, for a variety of reasons (file availability, internet problems, browser, bad coding, local cache, ISP problem) not everything downloads.
As long as the page seems to have all the information and nothing is apparently missing, I tend to ignore this.
When all items are completed, the status bar shows nothing.
