Well, you may be right. You certainly can't send events
to another TLB widget from a modal widget, which would
be the normal method of communicating in widget programs.
I don't know if you can control other widgets directly
from a modal widget. I've never tried it. But it wouldn't
surprise me to find it's not allowed, since by definition
the other widgets are not suppose to be "active" during
that time.

Cheers,

David
