Meenakshi encountered this on her laptop at home and had to install the hotfix. Be aware that after you install security update 873333 (MS05-012), you may find out that DBCS attachment file names are not displayed in Rich Text e-mail messages and you may receive a “Generic Host Process” error message (if you are on XP sp2).

You may also find that File names are not displayed in e-mail messages (where the format is Rich-Text) that include file attachments when the following conditions are true:

  • The file name contains double-byte character set (DBCS) characters.
  • The file name is longer than 42 characters.
  • An application that implements the IMallocSpy debugging interface may experience heap corruption after you install security update 873333
