I have and use two desktops. Same mouse for both, but have issues on one. Neither are networked, currently don't have internet access for either. Don't any viruses - yes I'm sure. W7 on both. Issue; I can use the mouse for 1 maybe 2 hours without issue, then it will freeze; can't click on anything on desktop, except to shutdown. If I reboot it will be fine for about 1 or 2 hours. Device manager says device is working properly, and like I said, I don't have any issues on the other pc. the only thing that may have caused this that I can think of, is I deleted ADW cleaner, a program which I liked, but without access to internet, could no longer keep it updated and didn't need it anymore. Its a program that doesn't have an "uninstall" heading in the uninstall program section. I suppose I could try to "restore" to prior the occurrence, but thought I'd see what any of you might have to suggest. any thoughts? Thanks. Dave.
