I have looked at a tremendous number of sites trying (unsucessfully) to find a problem similar to mine. I have a Gateway M-7315U laptop runing Vista with all the service packs and updates. I've installed 2 different wireless mice, one by logitech, one by microsoft, both have the tiny USB receivers. Both self installed, and both seemed to work well for the most part, but when I go through the process of placing the laptop into sleep mode and then later "waking" the computer back up, I get a black screen asking me if I want to start Windows normally or give me options to start in safe mode, etc. When I remove the receiver, everything goes back to normal. I even downloaded additional drivers from Logitech, but that didn't change anything. Has anyone else experienced this issue and if so is there a fix?
