How do I get rid off, or catch this error ??
When I shutdown my widget program by clciking exit, in my menubar, I can
reset colors, structures, the whole thing.
But when I click the Top-right-cross (Windows) And top-left=box on Unix,
which shutsdown the current process, I get an error by widget_event,
that this one ('named by number') is not defined.
I wish to clean up the variables that I clean on pushing exit in the same
way and dont want 2 create errors.
How can this be done ??
Thnks Sean

I think you've scored the bullseye in one right there, Mark.
"Users" are as good a reason not to as any I know of.
Long Live TLB_FRANE_ATTR!
I vote for the old Keep It Simple, Stupid (KISS) principle when
dealing with Research Scientists. Give them a chance to &^%@* it up,
and they will...
Allow no latitude nor lateral thinking in the interface.
Put the fuzzies in a nice solid black box, outta sight of the users.
Show mercy to the poor simple things... ;-))
