Does anyone have a problem with the scroll freezing in SONAR Platinum when you move your mouse in the track panes???
This seems to be a new problem that I've been having lately.

what kind of mouse are you using ?
I know I had problems with a Logitech mouse and sonar a while back.
I switched mice and haven't had an issue since.
but to answer your question I haven't had any scrolling issues using mouse wheel.
(which is basically how I scroll everything in sonar.)
 
 
could be a graphics display issue though. you might want to make sure your graphics card/onboard video is up to date.

I'm using a wireless mouse and keyboard by Microsoft (Wireless Comfort Keyboard 5000).
The problem occurs when I hover the mouse over the track panes during playback.

have looked for updates to your video drivers ?

Yes, I've updated my video drivers and it's still freezing. I did notice something very interesting, every time I power on my Apollo Firewire interface my CPU spikes through the rook every ten seconds or so. Turn it off and it returns to normal. I've talked with tech support at UA and not surprisingly they think it's an issue with SONAR. (Not buying that crap though).
