Hello, I've got Parallels Desktop 13 for Mac Pro Edition running on High Sierra with a Windows 10 Pro VM. The Mac itself is running completely fine. However, the Windows 10 VM freezes a LOT... the freezes last between 5 and 15 seconds usually, and happen maybe 30 seconds to a minute apart. During that time, no keyboard or mouse activity has any influence on the VM. The mouse moves around the windows screen, and I sometimes see a windows spinning circle (telling you to wait). When it Unfreezes, sometimes II suddenly see windows pop up or scroll etc -- I also sometimes get application not responding message. It's almost as if the virtual hard drive access is very slow. Again, the Mac itself is fine and nothing else appears as if it's under load.
