flash (macromedia): I have a jpeg picture of a chorus and another of a stage curtain. I am looking
to build a Flash document that begins with the curtain down and, on a mouseOver
event, raises the curtain to show the chorus. Next time there is a mouseOver
event, the curtain will close.

Can someone give me a general series of steps and techniques that I would use
to accomplish this?

I don't have flash on this pc else I'd make you an fla.

If you are new to Flash then you should learn the basics of Movie Clips,
Tweening and Functions.

If you don't get much joy then email me sometime and I will make you an fla
when I get back to my normal system.

It is very easy, just requires learning the basics to get you started - that's
all.

Good Luck.
