I am having the same issues. If i put my machine to sleep, it will resume fine & everything appears to be fine. WMC sometimes open, but then crash & reboot after i try to change a menu. very annoying.
someone suggested this was related to Intel Quick Resume. However, this problem exists when i have this both on & off.
Additionally, I have had issues with random "wakeups" that typically occur in the middle of the night... thus waking me up. ugh.
do a search online...you will fine that me & you are not the only ones with this problem... appears to be a Vista issue.
At this point, i have given up on sleep, and just do a hard shutdown at night....not the ideal situation... but best i got at this point (i really dont want to leave my machine on 24hrs/day, when i only use it for 3hrs/day).
