I've installed Fallout (v1.1) on Fedora 16 with crossover-games 10.3. It works fine when I run it in a window.
Under Cedega, I could run it fullscreen (albeit a bit stretched) and that also seems to work under cxgames, except for one problem. Once I get to the main menu screen, moving the mouse down or to the right does nothing. Moving it up or to the left, however, does move the pointer, resulting in it usually getting stuck in the top-left corner of the screen.
Needless to say, I haven't been able to actually start a game fullscreen so I have no idea whether this affects actual gameplay.
Has anyone else seen this or know anything about it?
