Yes, that was my assumption (even thought I am using linux); and right
again, it is a very inconvenient place for it to be.  however in the
interest of speed of testing i figured i would make sure the log was
logging the way i want it to and then try to find some sort of wx wigit
to let the user of the gui name/save to desired location. meanwhile . .
. so you think it saved somewhere right?
