Nancy, I don't know the answer. However, you should run Disk Cleanup regularly to dump your recycle bin and temporary files. Could be that having only 512mb memory plus many mb in your recycle bin has something to do with the error. WinXP would run slowly with only 512mb memory. Also, you need to run AdAware from Lavasoft to get rid of spyware and junk cookies. I've seen computers so clogged with spyware they would take twenty minutes to get to the regular screen on bootup, and five minutes to respond to an entry. The spyware was "phoning home" like crazy. I ran AdAware and the machine ran fast again, and the owners thought I was a true computer whiz.

This is the first time for this message but I have had other run time error messages but they are not frequent. I have Windows XP with AOL 9.0SE running on an E machine with a 100G hard drive and 512 memory. The computer is running very slow. I was going to do a defrag but it said I didn't need to. Also ran Registry Patrol and I have the AOL McAfee security suite and have dumped temporary files etc. I do have a very large recycle bin, could this affect anything? Nancy
