KEEP YOUR UPDATES RUNNING. DO YOUR DISK CLEANUP...DEFRAGS... AND MAKE SURE YOU ARE SHUTTING DOWN YOUR COMPUTER RIGHT WHEN YOU ARE FINISHED WITH IT... IF THE PROBLEM PERSISTS THEN YOU NEED TO REINSTALL WINDOWS. SORRY AND GOOD LUCK

Windows 98se is a little like working on a model T ford. (hard to get parts.) I vaguely remember that very problem. I made me crazy. So I upgraded and no more problem. Sorry. Good luck.
