There are things that are not "very different", yet still can't
be handled by the single-double-single click callback sequence.

Thank you! That would be great.

fl_delete_group() isn't in forms.h 0.88. It's in the library, though. Does
it delete the objects in the group as well as deleting the group itself? I
assume that the group and the objects in it still have to be freed explicitly
and individually?

I didn't see this behavior in 0.81, and also I don't see it for all
objects in 0.88. Some of my groups have more than one input object. When
the group is hidden, only the callback for the FIRST input object is
called. This behavior is consistent throughout my program, but since
I can't construct a simple demonstration, I suppose I'll have to keep
looking for a bug...
Thanks for all your help!
