WinXP Pro SP2. No other security software of any kind. Since installing Blink Personal 3.1.1 (looks & works great except for this!) I have experienced Outlook 2003 locking up more than 9 sessions out of 10. (The 1 session that did not lock up was very short.) This lockup occurs under my administrative privileges account and my limited access users account, in both off-line sessions and on-line sessions. There is no one action that brings on lockup. In about 1/3 to 1/2 of sessions Outlook never even gets fully loaded before locking up. When locked-up, the sub-window "End Now" can not stop the process, Windows Task Manager must be used. Please let me know what I should try or work on.
(I do have some recent updating to do and perhaps an Outlook update is among them. I will work on the updates on Monday and let you know.)
