I have a few pretty heavy-loading CPU projects. There are also a lot ot automated parameters in these projects. When i move mouse over the automation lanes (like just move mouse from bottom to top over the lanes), the CPU is becoming overloaded and it starts clicking and all that stuff.. i believe that this happens because of lot of mouse pointer changes. Yeah, there's a workaround -- just move the mouse around the whole automation panel, not goin' in, but that's a little frustrating )
Win7 x32, core i5.
