after months of toiling over this thing, I finally found the culprit. Gozilla, which I used 2 years ago and uninstalled 1.8 years ago, left behind a dll causing all teh trouble. a little registry touching up here, a little file deleting there, and the problem is fixed.
I am having the same problem. Do you remember the names of the files you deleted? Please help as you are the only one i know that has this problem.
THanks
Actually, I have a strange but workable temporary solution. I have seen various resolutions on the internet that include going into regedit and adding a line to tell IE to open attachments by extension name (such as .exe), but one that works immediately is to FORWARD the file to yourself without actually sending the file. You are just basically opening it into composing mode. In the attachment area click on the file that is being forwarded. Click "open" from right clicking on the mouse. The file should launch. If it doesn't, try saving the file to a folder on your desktop. Sometimes it won't let you open the file, but it will let you save it. Don't tell MS people. They might eliminate the temporary fix!
