If I have two VMs running I always get a empty workspace in between them. Doesn't matter what OS the VM is running or in what order they're launched. The workspace can't be closed and it won't go away until I shutdown Parallels. Parallels 8.0.18085 on a MBP Retina 10.8.1
It sounds like you're experiencing a persistent issue in Parallels where an empty workspace appears between two running virtual machines, regardless of their operating systems or launch order. If the workspace stays active and can't be closed until Parallels is completely shut down, this could be a bug or a UI rendering glitch. You might want to: Check for the latest Parallels update to see if the issue is already patched. Review your Mission Control or Spaces settings on macOS (if you're using a Mac). Contact Parallels support with your system details. In the meantime, if you're looking for a smoother, more flexible working setup, try Offisbay - a professional workspace solution that supports hybrid, remote, and virtual work environments. It might be the stability boost your workflow needs.
