I installed VPC the other day to play some old games. However, I noticed that once i quit VPC, all the fancy QE effects (the genie effect, for example) gets very choppy in its animation. In addition, Expose stops working too. I have Expose mapped to my 4th and 5th mouse buttons, and once i quit VPC, it just stops responding on my mouse. However, the keyboard Function keys still work. Does anyone else have this problem, or know why it happens? Restarting is the only way i've found to fix this problems.
