Here's the problem: according to your code, you want the pushed button
bitmap to appear when the object's D_SELECTED flag is set.  To get the
result you want, you would have to clear the D_SELECTED flag after the
mouse button is released, meaning you would have to write your own handler
for MSG_CLICK.

However, there is a more fundamental problem here: if you _do_ de-select
the button after clicking it, what effect is it going to have?  What is
this button meant to do?

Perhaps a better solution is to set the D_EXIT flag on the object, causing
the dialog to exit when the button is pushed.  Then, process the button and
re-enter the dialog.  When the dialog reappears, the button will be
deselected again, and you will get the effect you are looking for.
