I am taking an existing system designed for FMapp access and making it IWP accessible. I did some interesting things with dialog boxes. Now, I am having trouble with the images I use as buttons. It is really quite odd.

Some of the images will not work as buttons. I have transparent icon images I bought on the internet sitting on top of some gradient images (also transparent) I made with OmniGraffle. The OmniGraffle images work as buttons but the downloaded icon images do not. The OmniGraffle images are GIFs and the icons are PNGs.

Any clues?

Thanks for any input you can provide.

I've found that in IWP, if you stack an object on top of a button, the area of the button that is under the object will not be clickable. The solution is to group the objects and reassign the script to the group. Bit of a pain if you have a lot of buttons.
