Has anyone else encountered this little annoyance? It occurs when you return to your computer after the screen saver (of any sort) has been activated...2 or 3 blank buttons are left in the control bar at the bottom of the screen. When you click on them, they disappear. No big deal, just a pain in the ass. How can I stop them? Is it a bug in the particular screen saver I have? Same thing happens to a buddy of mine.
