A shot in the dark here, if you are running windows xp, check the following: Right click 'My Computer', select Properties/Hardware tab/Device Manager/plus sign on 'Mice and other pointing devices/right click ps/2 compatible mouse (or whatever is listed)/select properties/driver tab. What/Which driver is listed for the mouse your using now? Maybe click rollback driver? If this helps, just an FYI that one of the ''Mod's'' suggested that you normally don't need to install the drivers for a 'mouse'. Post back if this doesn't help so someone else can maybe give a suggestion. Don't forget 'System Restore' to go back to a time before you installed the other mouse.
A couple of days ago I was installing a Kensington mouse I have but once I got it installed and used for an hour or so I realized it wasn't as good as I remembered so I uninstalled it.OK so no probs there but for some reason now when I start up and get to my desktop I get "SHOW BUTTON ERROR" Error accessing Kensington Mouse Works Driver From Show Buttons Applicat.Then I can just click OK or X it out.Can anybody tell me how I might get rid of this?.Thanx
