Ok, I figured out it has something to do with the screen set I am using. I have attached the screen set that I am trying to use AND the one that I added the 2 lines to. I tried deleting the 2 lines that I added and the screen still would not load. If I used a different screen set (wx6.set), everything loaded fine, as well as my default toolpath.
I know, I should have made a copy of the screen set before changing it, but....I didn't. As stated, I am just getting started and am not connected to any machine, just playing in SIM mode. I am trying to also get a PoKeyes module installed, but I deleted the plug ins until I get this figured out.
As far as I know, I did not change anything other than the 2 lines shown in an earlier post and the file 'compiles' without any errors.
Thanks for any help.
