With Avast 4.7.986 running, Outlook 2007 under Windows XP Pro x64 will periodically freeze if a “Send/Receive” occurs while I am editing a new message. The symptoms are:
all responsiveness of outlook or the edit window will freeze, including mouse
system tray will show icon indicating messages are being received
outlook will unfreeze
avast globe will spin
additional messages will be received (system tray activity) and the same freezing will occur
