geographic coordinates don't work

[Donlad Harter]

I would like to use geographic coordinates for my main window. My only 
layer is georeferenced DRG which uses the UTM projection.   It doesn't 
work.  If I change it and the extents to UTM it does.  How can I use 
geographic coordinates?  I have also noticed that my map file won't work 
with the layer status "on".  It has to be "default"
Here is most of my map file.:
