For some reason, whenever the mouse drifts to a top corner of the screen while playing (the tested games being Morrowind and Oblivion) and I click it takes me out of the game and back to my desktop, effectively freezing Oblivion when I try to go back into it. This started a day after I reinstalled Morrowind (I have also uninstalled it now btw).
EDIT: Sometimes it's actually just CLICKING in the game, no matter the position of the mouse.
None.
Oblivion is a very buggy and inefficient engine, and it does NOT like being minimized. As for actually
getting minimized, I am unsure, unless you have applications running in the background, especially virus scanners, firefox, ect. that might update or refresh themselves while playing.
Show them your butt, and when you do, slap it so it creates a sound akin to a chorus of screaming spider monkeys flogging a chime with cacti. Only then can you find your destiny at the tip of the shaft.
