New Applications folder window opens always half outside the screen

Question

As in the subject, only the first time after a log-in or finder restarting, when i press shiftA to open a new window of applications folder, it opens always in the same ugly position, i.e., on my right side of the desktop, half out of it, half inside. This happens only with this folder. If after restarting finder, restarting the mac, log-out log-in, I press +N to open a new window, it opens correctly on the center of the screen. If I try to grab the new applications window either in the center of the screen or in whatever position I want, next log-in, reboot, etc... it opens in the ugly position as I mentioned.
I tried deleting .Ds_Store file in it, deleting com.apple.finder.plist, repairing permissions (both in leopard and by using the installation dvd), clearing caches, executing maintainance tasks, searching google, asking in it.comp.macintosh, praise the lord, but nothing. Now I'm going crazy, so I need to solve this.
Ps: Maybe this problem start when I installed magnifique. It's an applications that let you change leopard themes (since shapeshifter works only on 10.4). I uninstalled after two days, being shure to delete its preference files and any other stuff that could have been reconducted to it, but the problem is still there. I tried creating a new user and the problem still exists.

Hm, I guess that makes sense - the idea is to save power; but the process of trying to transfer control between display interfaces on the fly would have to be somewhat perilous.  This (hot swap of display interfaces) is just not the kind of thing that would normally be expected by software designers.
Are the two display subsystems made by nVidia?  If not, I'd imagine it to be a practically impossible task to get right.  GPU makers aren't normally friendly with one another!
It makes sense that a manual switch to the more powerful GPU would be needed to run Photoshop properly, as complex as it is.
