Hi Andre - it sounds like maybe VM has no persistent desktop. I know this sounds odd, but depending on the way in which the VM is set up and accessed, it can be running without a desktop. BP will still run, and a process that does not use the desktop will work, but if the process tries something like a global mouse click, activate window or a screenshot, it will have a problem. As a test, make a process that saves a screenshot using the attached object. Reboot the VM and run the Log In Process. Don't connect to the VM. Run the test process and if the resulting image file is all black, then it would suggest the VM desktop is not present, and maybe you'll need to talk to your IT guys.
