Hi Carl. I'd like to help, but I really need to see your code. Again, a very simple example...of your item renderer, and the mxml, and some actionscript that shows what kind of a change you're trying to make...will be necessary to really help. I don't see your item renderer code in the post below.

I really need to get this solved, or I'll have to throw out the entire app and build it in something else.
