When I move curser, I am erasing entire screen! what's going on?

I have a 8 month old macbook pro that suddenly turned into a spoiled brat. Everything seems to have developed "problems"...but my most recent one is, occasionally my curser decides to erase my screen to black as I use it. Almost as if I were using it in a paint brush mode and the only way to stop it is to force shut down with control>command>del. Why is this happening?

Get a Self-Powered Hub, your drives are using more power than the USB bus can supply.

If your camera shoots DVCPRO HD to P2 cards...like the HVX200, HPX170, HPX500, HPX2000...then it will come in as DVCPRO HD. Only AVCIntra P2 comes in as ProRes. DVCPRO HD P2 comes in native.

Hi Dan - I'm not sure I know what you mean by 'kick in Expose', can you please explain?
It's a weird one as it doesn't happen all the time. Could it have anything to do with running Apple TV and the MacBook 'thinking' there is another display (extended desktop) and playing the video there?

After migrating to a new MacBook Air from an older MacBook, iPhoto gets stuck on uploading cache, it just "spins" forever. I downloaded a new iPhoto app and replaced it but when opened it just does the same thing? What is going on?

After migrating to a new MacBook Air from an older MacBook, iPhoto gets stuck on "uploading cache", it just "spins" forever.

Is there a better app?
Thanks, Chris

Take the system to an Apple store to be fixed or replaced as the one you have has defective hardware.

When I move from window to window my screen has weird pixels

Hello,
Sometimes when I move from window to window there are appeared weird pixels on the screen.
It seems that the image is not processed fast enough.
Any advices?

hello, have you set any other dpi value in your operating system than the default one (96dpi)? more information about that is available at http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/display_use_large_or_small_fonts.mspx

I have iphone 5c. Having email problem. Does not delete emails showing in inbox from date 8/27 thru 9/23. When deleted, these same emails repopulate in inbox. What is going wrong? How do I fix the problem?

Ihave iphone5c. Does not permanently delete emails showing in inbox. When they are move to Trash then inbox at first shows empty. However if you leave Mailbox and return then all the emails that were previously deleted and now repopulated in Inbox. I have tried various things like marking them "read" before deleting, then moving them to Trash, and they still return. What is going wrong and how do I fix the problem?

What your describing sounds lot like Nortons anti virus, but other do it to.
Multiple copies of the same email over and over are almost always anti virus incoming mail scanning. Turn off scanning and the problem goes away turn it back on and it resumes.
My guess is that your filter issues, and search problems are also related to this uniquitous and most ignored security tool that messes up far more than it should..
Deleting the index
I assume you mean the global-messages-db.sqlite. if you don't close Thunderbird and delete it now. Searches will be incomplete until it rebuilds and the time to do that will have a lot to do with how much mail there is and how busy the computer is.
Now create an exclusion in your anti virus program for the Thunderbird profile folders. My guess is it is trying to scan the files in your profile every time Thunderbird tries to open them and generally turning things into a tug of war, which Thunderbird looses as it just does not wait around if files are locked. It expects exclusive access to it's files immediately, not in 10 minutes when the anti virus has done it's thing. So things get added to the index but not removed. Mails don't move as the destination or source file is "in use" etc.

Why do panel array positions change when I move to a computer with LCD screen?

I wrote a program in the lab and then moved it to the production area which
has a computer with an lcd monitor. The program has 3 arrays of clusters on
the front panel and each contain both controls and indicators. When I moved
it to the production computer the 3 array moved somewhat from their proper
positions. Also, each one moved a different distance. I wanted them to be
aligned so I ended up moving them out of alignment on the uncompiled copy so
that the production copy would be aligned correctly. Is there something
funny about lcd screens? Labview property node reports they are already
aligned and of equal height. Is there a way of forcing the arrays to align
no mat
ter what computer it is installed on?

I've seen this before. If the resolutions are different it scales certain fonts
differently causing your controls to move. You need to make sure your using a
common font type and size between them or change your resolution on your desktop
to match the lcd's.
You can check the font on both machines to match them. One might have Arial 13,
20, 28 and the other Ariel 14, 20, 26. If you pick 20 it will go back and forth
ok, properly scaled.

Why does an image in Preview disappear when I move the window from my laptop screen to my external monitor?

I have an external 23" Cinema display connected to my MacBook Pro. When I open a file in Preview, moving it from either screen that it was originally on (laptop>LCD or LCD>laptop), the image disappears or "blanks". Only zooming in on the image will re-display it. Any ideas?

Still investigating this problem.

How can I solve this problem? Please help.

This same exact thing has happened to me SEVERAL times since I have upgraded to Lion. Thanks to the solution provided, I was able to get my Finder Windows to reappear. Thank you cabooth. I hope Apple fixes this in their next release - I'm getting awfully tired of having to do it.
