Hi Evan,
I don't see anything clearly wrong with the fix. I haven't gotten wind of anybody really using the Cholla stuff in
recent versions of Cubit, though if they changed something there I'd think it would have been for a reason involving its
usage. I'll ask any of the Cubit dev's I see at the IMR in a month (Rajeev, remind me, or let's gang up on them there).

The current releases of GRUMMP depend on CGM 12, so we asked them to upgrade from version 12 to version 13.1. They agreed to do that but ran into a problem with the CGM code along the way.
