... but, of course, you can use David's tvread routine to produce a bitmap file
with a temporary name and use that for your button. Ugly but effective ;-)

Thanks for the heads up ... i decided to get around it by creating a
compound widget, involving a draw widget, that returns events as if it
were a button widget. I believe i read somewhere on David's site that he
had written a routine like this in the past ... good idea David!
