CAVS and Spamihilator with MS Outlook keeps asking for password

I know that others have had this problem but I don’t see it on this forum.

I have two machine running CAVS and Spamihilator with MS Outlook (not Outlook Express). One of the machines works OK but on the other one if I have e-mail checking turned on in CAVS then Outlook persistently prompts for the password. When I turn e-mail checking off it works fine. I’ve tried this with more than on version of Spamihilator and the problem is the same and it has never been a problem with any other AV software I’ve used.

I’ve been in touch the Comodo support but they told me that as CAVS is still Beta this was a better place to mention this problem.

I’d be interested to know if anyone else has anything similar.
