I just did a Repair Install. Most things went well.
One glitch is that when I try to open .htm files in Favorites I get the prompt shown in the screenshot. I just click Open, but it is a nuisance. This does not occur with .htm files already downloaded to the hard drive.
I assume this is caused by a setting in IE Internet Options (perhaps Security or Advanced tabs), but I cannot determine which one.
Can you tell me the setting?
I already checked in Default programs that IE is the Default program for .htm and .html files.

Good Grief! I cannot find how to add the screenshot.
In text, here is what it says.
What do you want to do with xxx.htm?
open (the file won't be saved automatically)
save
save as
