Hi, I recently upgraded from Parallels 7 to 8 and use both Windows 7 and a company build in-house Linux (based on Linux 2.6.23). The issue is Linux guest eventually becomes unresponsive to keyboard commands and I have to keep stopping the guest OS. I use our Linux daily for testing and work and this issue is preventing me from doing my job effectively. I should add that I access the Linux guest OS using SSH from my Windows guest OS so I keep the Linux window minimized. I may have to downgrade back to Parallels 7 but would rather not since I paid for 8 and do expect it to work. I've included the parallel logs and hopefully they will help identify the issue.
I sent in a bug report and in the meantime downgraded back to Parallels 7. Now everything is working perfectly.
