Not guilty here, at least not on purpose, someone else might have put in 
a patch to enable/disable the buttons.  But in the disabled state they 
should still show the black and white version (using the alpha channel).

I looked at it when I saw Andrea's post but can't figure out why they 
show a grey block instead of a black and white version of the button.

This is a problem I do have on the Win 2000 with my own app/images, but 
on XP the alpha channel stuff works correctly.

I'll have another look at it.

See you
