[Zope] External Editor stopped working for me

I love the External Editor product - it's worked flawlessly on a Win98 system. I just moved to a Win/XP system. External Editor worked for about a week, but now for some reason always fails with: FATAL ERROR: {Errno 1] No such file or directory: C:\\Documents and Settings\\Roger\\Local Settings\\Temporary Internet Files\\Content.IE5\\mumble\object[1].zope I'm wondering why this worked for awhile, and now stopped. And for some reason, my actual directory structure now includes ...\Local Settings\Temp\Temporary Internet Files\Content.IE5 Not sure how the extra Temp got in there, or how to circumvent it. Thanks for any advice.
