Just to let you know; I just found out, why it didn't work on my comp. I have the ROCCAT Kone mouse and Shake doesn't work because of that. I got my other mouse - MX 518 - connected today and Aero Shake worked just flawlessly with that mouse. Weird, but yeah. It is what it is, eh? Problem solved! Edit: I investigated even more and found out, that the Mouse wasn't the problem at all. I tweaked the USB port a bit by raising the polling rate from 125MHz to 500MHz. Now I'm back to 125MHz and voilĂ : it freakin' works.
