If not, my best suggestion is to reinstall IE, and if that doesn't fix it, reinstall Windoze. Remember, we're not M$ support specialists here. Free advice is worth what you pay for it and little more :)
If this works and you don't want notepad for your editor - simply rename notepad.exe in your windows directory (usually C:\WINDOWS) to something like notepad.ex0, copy your favourite program into your c:\windows directory and name your copy of your editor of choice "notepad.exe" :D
