It does not even get fully drawn. In some cases i saw progressbar stopped on 15%,20%,70%, always different values. Then "Saving" window dissapers and attachment is not opened. It is possible to save and open attachment though. As far as i mentioned this happens only if attachment name contains national characters (russian in my case). BR Evgeny Reproducible: Always Steps to Reproduce: 1. Name the file with national chars, i.e. ÄÏËÕÍÅÎÔ.doc 2. Send it to yourself 3. Get new messages and try to open attached document. Actual Results: It happens what i described before Expected Results: Open attachemnd with default application
