MORE INFORMATION

Steps to Reproduce Problem

WARNING: The following will cause an Internal Consistency Error followed by a GP fault.

Execute the following program. Be sure to select a different font in the GETFONT() dialog and choose OK.

   MODIFY WINDOW SCREEN FONT "Arial",10     && Change the screen font
   m.fontstrg=GETFONT()                     && Must change the font
   x=fontmetric(1,"Arial",12,"")            && Call Fontmetric
   y=fontmetric(6,"Arial",12,"")            && Sometimes it takes twice

There will be an ICE followed by a GP fault, generally on the first FONTMETRIC() call, but sometimes on the second.
