I have a logitech marble mouse trackball. the last 2 or 3 days I have noticed an issue where it won't click in a certain spot of an app. I can always click on the finder then back on the app and it will work fine again or sometimes if I resize the window. FYI: I use the logitech control centre sw under panther x.3.2 to program the scroll and also right click on the second button. never had an issue with this sw under panther before and I have been using panther since nov. any ideas as to what would cause this odd glitch?
