Well, from time to time I’m not an exception and I need help :-
I have MS Outlook 2007 configured to start 6 minutes after logon (using Startup Delayer).
The avast! plugin is not being loaded. Although it’s show as loaded, although the spash screen had popuped normally before.
If I close MS Outlook, and some time later, start it again, the plugin comes back.
I bet on a conflict with Google Desktop plugin, which got “disabled” status sometimes.
