The only other issue I've had is that I can't run the game in fullscreen because my mouse cursor will disappear so I have to run it in windowed borderless. However I could care less about that since I want to run it in borderless, but the steam tracking thing is an irritating annoyance that I have noticed everyday playing. Not to mention by buddy pointing it out how he has "more" playtime despite being half as far, just reminds more that it isn't tracking right.
Both problems could be caused by *gasp* windows vista.

i know the fullscreen cursor issue is.
