Perhaps so.  I use another, perhaps equally clumsy method:  After
creating my buttons, sizing them, iconizing them, etc., I snapshot
the screen, extract just the button images from the dump, turn the
black parts to gray with the paint bucket in SuperPaint, and then import
the result back into HC via the cliboard, and paste the bitmap back
"under" the buttons.  When I want to gray out a button, I just hide it,
and the greyed-out bitmap under the button then shows through.  This
technique requires a bit of munging around to set up, but once you have
done it, all it takes is "hide" and "show" commands to grey-out and
restore the button.
