Windows NT Mail Client Does Not Handle Long Filenames Correctly

SYMPTOMS

When you attach files with long filenames including spaces (for example: "This is a long name.txt") from the Windows NT mail client, they appear to attach correctly, but when you try to open them you receive the error, "No application is associated with file name."

NOTE: Long file names without spaces (for example: "Thisisalongname.txt") work correctly.

The same problem happens when you try to Save Attachment. The dialog box offers you the complete filename of the attached file, but it does not allow you to save it with this name.

   "This is a small file.txt" becomes  "thisisas"
   "Thisismylongfilename.txt" becomes  "thisismy.txt"
