What Versions Are Affected?
I ran into this problem a couple days ago...I too would have to reboot the virtual machine to make it work. One time, however, the virtual machine would not respond and Parallels would not stop/restart/kill the VM. I tried everything on the Mac to kill it....even using the unix "kill -9 pid" command. My Mac wouldn't even restart or shutdown. I had to unplug it to shut it down.
So I have two questions: first, is it only the 32-bit versions of Ubuntu that are affected or is the 64-bit version affected as well. Second question: Was this problem fixed in build 3810?
Thanks for the info!
