Rhywun: Hi just purchased the game for Mac. Played it many years ago but there is a major issue with current hardware that is making the game unplayable today :(

Specifically, I cannot move the mouse pointer in-game to the singing icons or the map, unless I "throw" the mouse very hard in each direction. Otherwise the cursor kind of wiggles but remains centered on the player as I try to move it around. It is a Magic Mouse (wireless). Any ideas? Thanks
