I don't think I can avoid MESSAGE. It is the only way I know
to throw an error. I have tried setting the !Error_State fields
to "success" values, but to no avail. I think the problem is
that the error occurs during a widget event, and I think
the RSI routine that distributes events is catching the
error there somehow. I would LOVE to see some documentation. :-)

Cheers,

David
