--- Comment #1 from David turbolad995@hotmail.co.uk 2012-01-16 12:20:00 CST --- VERY CLOSE to being fixed. The mouse sensitivity now works much better when playing Audiosurf in Wine version 1.3.37 - and you can change the mouse speed by pressing ESC during gameplay and that works better.
Please keep up the good work. You're very close to having the mouse movement in Audiosurf working as if it were being played in Windows 7.
