cannot turn off sharp boundaries in pre-existing molecular surface

[Elaine Meng]

Users are unlikely to try this, so you may want to lower priority.

If I create an SES (sharp boundaries default true) and then try to remake it with sharp boundaries false, redraw halts. This problem does not occur if the SES is initially created with sharp boundaries false. If problem is hard to fix, could disallow sharp false for SES.

Example:
open 1zik
surf
surf sharp f

An error occurred in drawing the scene. Redrawing graphics is now stopped to avoid a continuous stream of error messages. To restart graphics use the command "graphics restart" after changing the settings that caused the error.

Fixed.

[Elaine Meng]

I’m still getting this error in the 6-25 daily build.  Maybe the fix wasn’t committed yet?

[goddard@…]

Unfortunately I forgot to git push the fix Friday in my rush out of the office.  The fix will be in tonight’s builds.
