>that's the mouse with the browser scroller between the 2 buttons? no problems with those (yet)

Exactly -- that's the mouse type where my vfp app and PC SAS do not work correctly, the Click events don't fire in my app. In PC SAS, it's the opposite problem -- just holding the mouse near anything causes the Clicks to fire, causing the user lots of grief :)

Maybe we just don't know how to use/set the mouse features? It's set to Windows default in Control Panel, and appears to be using the correct driver...no documentation came with the mouse, unfortunately...
