Hello
We use AppV 5.0 bèta in our test environment to deploy some applications. We use a virtual disk to store the userdata in.
We have a strange problem: often when logging on and trying to start a virtualized application, we get an error saying that a device attached to the system is not functioning. Logging off and on again solves this problem.
I have checked the eventlog, but I can't find an error message about this issue.
I have a screenshot attached (it's in dutch).

What could be the cause of this problem (I don't think it's really appv related, but I don't know where to start searching. Everything works ok, and the virtual disk is accessible and the user profile loads correctly).
Thanks for any advice!
Regards
Geoffrey
