We have a number of Windows XP SP2/SP3 machines that after the desktop "locks" after our inactivity timeout, the screen will go into a continuous flashing or flickering of the Novell login box.

The only method I have found to resolve this is to power off the machine hard. The problem will usually resurface for the user after a couple of days.

I've searched the forums and it looks like someone had this problem way back in 2006, but there wasn't a solution posted.

We do have Zen 7, NW 6.5 and the latest Client for XP.
