hey, i just plugged in my logitec mx 500 and it doesnt feel normal. its hard to explain.. it just ...doesnt feel normal. is this a known differnce with OS X and how it controls mice? or a logitec driver issue? i was thinking maybe its something to do with acceleration or something. the system preferences doesnt really have a stunning array of options. this is kinda annoying in rtcw, its like it moves to slow and then to fast. does anyone know what im talking about?
