Gracious monks,
I have sought long and faltered. No where can I find a simple example of how to change a button's appearance when it is pressed while its associated callback runs. It's no good to see the appearance change after the callback finishes, I want a doohickey as simple as changing the button's color while its callback runs. And of course I'll switch the appearance back once the callback/sub is done.

My problem stems from some Win32::OLE calls I'm making that do lots of processing/formatting with Word. They take long enough such that a user might not notice that:

"No matter which value is specified for the -relief option, when the button is pressed with the mouse, its relief will change to 'sunken'." (from Learning Perl/Tk by Nancy Walsh, p. 69)
I want something more dramatic than a sunken button. It doesn't have to be the AIX "running man", a simple change of colors will do--I just can't see the option to do it.

Thanks,
Brig
