This happens every week when a scheduled scan runs, and it never happens when I run a scan manually:

"The fax receiver failed to open." When I cancel that message, I get another pop-up that the Delrina WinFax receiver failed to open.

I also get (and it is expected) the "may we run Spybot when you restart due to unfixed problem(s)" dialog; I've tried doing that, and Spybot finds no problem(s).

Why does the scheduled scan differ from a manual one, and what do I need to do to fix the problem?
