Fix Version/s: None
I had AC97 driver installed here which might play a role and it's quite reproducible here (not sure whether it happens without as well). unrelated
steps to reproduce:
-run the game
-switch to fullscreen via menu
-close the game via menu (if that does not trigger for your specific game try alt+enter to switch out of fullscreen or winkey to switch out of fullscreen)
You will see ros desktop and the mouse pointer is in top left corner and cannot be moved at all anymore. Lbreakout is still visible in taskbar. You cannot alt+tab to it anymore. But you can kill it via taskmgr. Mouse cursor can still be not moved anymore then
The only way I found to fix the mouse is then to start and close the game again via Keyboard.
