They do say the simple things can be the hardest.

Reboot bundle works OK on a scheduled reboot (for patches etc) if I'm not logged in. If I log in and wait for the bundles schedule to kick in it appears to start working and shuts down apps etc. After 'Saving your settings' it gets to a black screen with mouse pointer and then hangs. Everything appears to close up OK but...

Any logs that I could set? Any one with the same issue.
