I am having problems in making OE6 my default email program. Also, I am
having the problem of multiple IE windows (55 to be exact) popping up when I
click on an email link in IE6.

I have tried the following suggestions but nothing has worked:

When I click on the "Make default" button in OE6 under Tools/Options, the
setting is not saved then next time I back into Tools/Options.

Finally, I believe that the mailto key in HKEY_CLASSES_ROOT is corrupted
because when I click on it, I get the following message "Cannot open mailto:
Error while opening key". I cannot delete the mailto key either.

I would appreciate your help for fixing this problem. Thanks.
