I can't get it to actually open the logfile here, spits out a box with 
the error, then opens the selector screen.  Or do I need to touch the

by hand for onesies and twosies projects.

People having trouble with vz bouncing email to me should add the word

stupid bounce rules.  I do use spamassassin too. :-)
