What a horrible experience. Installed the new Parallels, but the Windows 8 VM makes noises and interrupts itself every 5 seconds.
Was just about to post the same thing. I keep hearing the "device connected/device disconnected" sound every few seconds. I ended up just muting the virtual speakers, but would love an actual fix
I tried the same thing, but the interruption (2 second periods of non-responsiveness) is intolerable...
There's a workaround that worked for me (and several others): http://forum.parallels.com/showthre...multiple-times&p=698386&viewfull=1#post698386
An update posted yesterday seems to have fixed the problem. Although I couldn't find anything in the release notes to suggest this particular problem had been addressed, I took a chance and removed the boot flags I was using yesterday, and so far the mouse remains connected to the VM.
