HI, Yes it's a USB mouse, and I started the computer up without going into safe mode, that's when it came up with the desktop restore screen,, I had no way to get to the button because of the mouse not working. I use the key on the keyboard between the windows and Ctrl key on the right side of the keyboard and that seemed to get rid of the desktop restore button, but now I am not sure it really helped. I could use the windows key to get to the start menu and shut the computer down. But it still comes up with the fuzzy background on the screen and the mouse doesn't work. Like I said it works fine in safe mode. Does this help any?? Debbles
