I have a very simple application that has one screen and one button. The main screen has a verticalFieldManager with a BitmapField inside it, and one button beneath the bitmap. I want to be able to overlay another image on top of this when the user clicks a button. The overlay image is a PNG with transparent background, and this is important for design, so I can't use popupscreen or a new screen because the backgrounds are always white by default, and I've heard alpha doesn't really do the trick.

I guess what I'm asking is if anyone knows a simple way to...

A) take a standard verticalFieldManager and overlay a PNG on top of the inner contents

B) overlay a PNG over the screen, no matter the contents

The basic functionality of this app was intended to be - show an image. on click, show another overlaid on top. on click again, remove the popup image.

I haven't found anything that addresses something like this online, but I have read of people doing similar things that utilize popupscreen and new screens in a way I don't need to do.

Hopefully this makes sense. Thanks
