661	traceback changing surf probe radius after hiding a patch	Elaine Meng	Tom Goddard	"open 2gbp
sel zone ligand 6 protein
surf sel vis 1
[... ctrl-click to select one patch in surface]
hide sel targ s
surf probe 1.45

I get a traceback and redraw halted, even if I show the whole surface again after hiding the patch (surf; surf probe 1.45).  However, if I skip the patch-hiding step I don't get the traceback.

Error in drawing scene. Redraw is now stopped.
