many thanks for the all the support.  its not a vworkspace problem, because we tested on a normal virtual machine on hyper-v without any quest software installed in it, and yes, it crashes also there.  thanks a lot
Hi  Is there anybody using GIMP succesfully on VDI Desktops with vworkspace? I have installed it, but it every time crashes after a few minutes working with it.   Marc
