LRM thanks, gives me some consolation that the fault is not necessarily something that I have created.
I loaded the HTML page into IE5.5 and did see green buttons (which I didn't see under FireFox), but they had no effect.
This surprises me in that I assumed that I assumed that the browser was just a vehicle to carry the Flashplayer. With the file locked as an swf entity, and Paradise 2 works, I am lleft confused.
