Thank you again samac1068.

And thank you Zettl. I had come to a similar conclusion myself & have now got the full card movie to work by putting the turning card into another clip & tweening the new clip across the stage.

I still can't get my head round why Flash should stop a clip tweening just because someone presses a button. It is not like the comand was _alpha=40; & then stop the tweening clip.

As I say, i think i have found a fix. It seems to work, but it leaves a bad taste in my mouth that I coudn't achieve the same without having to create another holding clip.

Thanks again for your help my friend.
