and also tryied: on (release) {getURL("products.html", window="mainFrame");

buttons are in top frame

can anybody help me
thx Milan

whats your html code look like?

I've had the same problem, and I couldn't track it down.

I finally made a Javascript function which changed a frames url which I called from within flash.
