Solved Vista x64 focus steel issue

Hi everyone

I've been using Vista x64 for about 4 months now and in that time I have been having this problem where Vista sometimes steels the focus from fullscreen apps such as games.

For example: I run a game, the screen goes black for a second (which it does in most games before the intro), then the game minimizes to the system tray and I'm back at the desktop. If i then try to bring the game back to fullscreen (using the mouse or ALT + TAB) it immedially minimizes to the system tray again, some games even crash. In the "micro second" that the game stays maximized I can see that the game has indeed loaded correctly, cos if I maximize the game a couple of times I see that the game is proceeding with the load.

Sometimes a restart helps, at other times a reinstall is needed. Some games I just can't run at all, and some runs fine all the time.

Now for what I have tryed:

All drivers, firmware and the BIOS are of the latest versions...
I completely removed my Nvidia display driver using "CCleaner" restarted and installed the latest one.
I tryed removing the "focus steel" ability from Vista using a reg file I found some where (I forget where).
Vista is of course fully updated.

If ANYONE has any idea why this is happening or better yet have a solution, please please post your comments, this really is driving me crazy. By the way, I never had this problem with XP Pro.

Thanks

Edit:
I found the trick I used to prevent the "Focus steel" in Vista.

1. Open Regedit.exe
2. Navigate to HKEY_CURRENT_USER\Control Panel\Desktop
3. Change the value of “ForegroundLockTimeout” from 17d1d0 to 0030d40

I don't know why this thread is set to "solved", cos it is not!!!

I think I finally found the problem...

It was a gadget in the Vista sidebar, at least I think so.

Anyway, the problem has'ent returned yet...
