Ok, it's me again.. (I hear you all sigh)

In my quest to beautify my program I'm replacing the dull grey command buttons with pictures that changes when the mouse is clicked to emulate buttons.

I have tried two methods.. One involves using an image list and swapping the image file over when the button is pressed and the other involves using several pictures and making each visible/invisible when the button is clicked. Both work but both produce a flicker as the button is pressed which, not putting to fine a point on it, looks pretty rubbish!

Is there any way of doing a sort of double buffer or an easier method to prodcue a smooth transition between the frames making them actually look like a buttons.

Cheers, Tim
