Hi all, I'm doing a class that contains several image controls. The class is intented to mimic a toolbar with buttons showing special effects when the user hover the mouse over one of the buttons and another fx when it's clicked. I control the first effect on the mouse enter/mouse leave events and it works ok, now when the user click the button the intended image do not show for some reason. I put code on the mouse down/up events to hide the image displayed while the user is hovering over the control and show the on-click image (and in the click event for testing purposes) but it didn't show.

What can be wrong with this approach? The click event is firing properly but the image still didn't show. I'm using image controls as buttons instead of regular buttons because I'm using png images with transparency and they do not show well on buttons without loading'em on a image control anyway.
