And there are one or two other object types (that have scroll-
bars) where using "Cancel" results in a segfault. The whole
thing in fdesign is quite a bit of a mess and I inherited it
with a comment of

/* Changes the type of an object by reconstructing it. A quite nasty
   procedure that delves into the form structure in a bad way. */

I fully subscribe to that and just added

/* And it looks a lot like a memory leak... */

:-(

I'm just looking at it but haven't found a fix yet.

                               Best regards, Jens
