I'm using Workstation 9.0.1 on a Windows 7 host with a XP guest system. Since some weeks ago the copy and paste between host and guest stops working sometimes. In the "guest isolation" (VM settings) copy and paste is set active and most of the times directly after starting the VM it works fine. But then it stops working and I'm not able to copy between host and guest any more.
I checked the windows XP logs and the only VM related warning entry I found was this one:
[ warning] [vmusr:vmusr] vmware::tools::UnityPBRPCServer::Start: Failed to register with the host!
It looks as it appeared about the time the trouble with the clipboard operations began.
Re-installing the VMware tools didn't solve the problem.
Any ideas?
