Flash Player 'Play' function moves to next frame

Hi,

I’ve got an app based on four frames with seperate events on each frame. The app is powered in AS3 and every frame calls stop(); and everything works well but the swf file in flash player has a problem where if the user hits control > play it moves to the next frame.

How can I stop this? A simple conditional would prevent it but errors are triggered this way from ongoing functions from a previous frame.

Please help.

PS Really value this forum!
