Parallels Desktop 5.0.9310, Windows XP PRO w/ SP3, and Outlook 2003. All MS updates have been installed. Has anyone had any problems with Outlook 2003 "hanging", and continually resending the same email if there is a large file attachment attached? I've had this happen 3 times since upgrading, and it's just my suspicion at the moment that the large attached file, or total size of the files attached, is related to the problem. Does anyone know if this has been officially reported? Thanks.
