------- Additional Comments From rethnor@gmail.com 2006-29-11 12:22 ------- I noticed somethign when I was playing everquest, well attempting to. This, Everquest has this jittery mouse won't move from center bug as well. However if you loadup everquest and go under options a new screen opens up, this appears to be an external application from the game it's self. When this window is open and has focus the cursor can move around the window just fine, but when the cursor strays from that window it is forced into the center of the screen. This makes me believe the problem with this but is that the main window size is registered as 0x0 pixels, so any mouse movement causes it to center.
I know this is pretty layman way to put it, I'm not familiar with debugging wine, but I'm about to learn some.
