Oh, my Gosh! June 96. Well, I guess I've learned a *couple*
of things in all those years. :-)
Cheers,

P.S. Probably you couldn't set a timer delay in those days. :-)

A timer widget AND a WAIT function!? Sounds like overkill to
me. I'd get rid of the WAIT function and let the timer do the
waiting.

Why do you use WAIT? You should be able to do with WIDGET_TIMER alone, I
think.
