Quartus II Hangs with NFS

Dear Forum,

I'm using Quartus II 13.0.1 build 232 64bit and OpenSUSE 12.3. If I place my projects on a disk accessed through NFS then Quartus hangs. The very same project placed on a local disk works without a glitch. I guess this is a locking files issue.

Is there an easy fix for this from the Quartus II side?

Thanks a bunch,

Virgil
