First, save such an attachment to any folder you like. Than use Windows Explorer to find out what the extension is. That's the part of the filename behind the last . (like doc in letter.doc). You might have to set an option to show extensions (not hide them) for known file types in Config Panel>Folder options.
Then, in Config Panel>Folder options>Filetyps search that extension, and find out what program is used to open it by default.
Post back what you find, and probably someone will be able to help you.

I have checked prior forums for this problem and I have yet to find a cure. When I open an e-mail attachment in OutLook Express, it opens using Note Pad. How can I change this back to the way it was originally? The grand kids have been using this HP with XP (sp 2) Model # is a450n This Note Pad thing is driving me nuts. Any help would be greatly appreciated. This problem has just started after this last week end. Thank you
