Error on shutdown of widget !@$%

["Sean Heukels" <sean77=cuthere=(at)dds.nl>]

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 ??
