I was going to try to duplicate the situation, but it wouldn't do it so here is what "has" happened(s). Occasionally I change my desktop picture & when I've rebooted, along the top of the screen, it says words to the effect " Do you want to wait for the program to shut down & then by the bottom, it says Force Reboot cancel. The first time it happened, several days ago, it ended up rebooting before I had a chance to read the full page. Earlier today when it happened, it mentioned losing something if it wasn't saved. If this is normal behavior for W7,ok. Some of the desktop pictures have come from desktop nexus. Other are just screenshots I've saved. I'm only bringing this up because I'm curious, its no big deal, thank you.
