Image on disabled button

[Richard Townsend]

Is there a known problem with images on disabled buttons on Tk8.4.4 ?

If I create a button widget using a bitmap as the image and make the button
disabled, not all of the image becomes stippled. The 3 left hand columns of
pixels and the bottom 3 rows of pixels are left unchanged. This is most
obvious if you use a black square as the bitmap.

If I run the same application using Tk8.3.4 this doesn't happen - the
stipple is applied to the whole image.

I am using Python2.3 + Tkinter to test this.
