Flv.stop(); problem

I am creating gallery with which to view flv files. I have the main menu on frame 1, and then 4 flv files on frames 2-5. The flv’s are being inported with AS3. I have created a previous or next bttn to navigate.

My problem is that if you click to view, say flv 2, and then click instantly to view next flv, flv 2 keeps loading and the audio plays over the next flv.

I have used this, inside the next/previous bttn to stop the flv loading…
[AS]
flvControl.stop();
[/AS]

It works, but not if you click instantly next or previous. It seems to me that if you click a fraction before the flv has loaded then the command

[AS]
flvControl.stop();
[/AS]

doesent work.

Any advice much apreciated.
