fry_Refresh() is pretty much the entire GUI. You'll have to open several of the GUI files to work out exactly where it's failing, as the MaxEdit debugger doesn't seem to open these files for me, instead just failing at that fry_Refresh() line.
Is this with the included example or your own code? If it's the latter, if you can post some that would help.
