Mysterious error messages

Archived from groups: microsoft.public.windowsxp.general (More info?)

I keep getting these pop-up error message boxes when I close Internet
Explorer or other OS elements, like Task Scheduler & some other bits &
pieces:

"iexplorer.exe-Application Error" & "Proxy Desktop:
Explorer.EXE-Application Error" telling me that specific memory addresses
cannot be read.

I suspect this is some conflict between installed programs or conflicting
settings in some program, but I don't know which. I'm not using a 'Proxy
Desktop' or virtual desktop.

Anyone have any ideas?
