I am using bitmapbutton on a touch screen.
Created two bitmaps for, raised and sunken for Up and Down.

The problem is the sunken effect sometimes is not visible. So when the use
touch the button, the button most of the time doesn;t apper as sunken!

I added the same sunken buttton as "focus", this time the sunken effect is visible,
but then the button remain as focused after touched!

Any idea how to tackle this???
