Thanks Mark - Distributed testing pays off again.:) What didnt work on my
work pc worked on yours and also my home pc. I am pleased to report that
events work as expected too.

I cant say that I have bothered to get flash working under my linux mozilla.
My primary interest is using flash as the UI for python apps (on win32 of
course). Not because I want to learn yet another gui toolkit, but because
creative types seem pretty comfortable designing really good looking UI
prototypes in flash.

A couple of sites have covered this from a VB perspective - this article
covers it in depth
http://www.macromedia.com/devnet/mx/flash/articles/flash_vb.pdf

Find a working demo attached below - click on the sphere in the flash
window, and python will respond and change the gui based on the event.

My next goal is to get this working outside of pythonwin, as a standard app.
Any further suggestions on how how to throw together a simple activex gui
container?
