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 
file first?

We did get the M101 function working here tonight, so now I can see the 
values of the #vars I'm using, which will help a lot when writing code 
by hand for onesies and twosies projects.
