This is one I've never seen before. In a WinXP SP2 environment, if you double-click on a folder, it does not open the folder, but it pulls up the Search for Files or Folders application. The computer does not have one of those fancy mice (nor the software for such) where you can re-program what the clicks do. Everything else I looked at in File and Folder setting, Mouse, etc, is otherwise normal. I'm presently scanning for virii and spyware, but I do wnat to know if anyone else has seen this and what was done to fix it. Many thanks.
