button - image on top

[wazza]

Hi all

I have placed a bitmap image ontop of a button:

the plan was to;
1) when the mouse is not near the buttons the image is displayed ontop
2) when the mouse moves over the button the image visible property is set to false, displaying the buttons caption
3) so when the mouse moves away the image reappears

im trying to get (3) working - however the image doesnt appear - it sits behind the button

is there a property to move it forward? or an alternative suggestion?

many thanks
