prevent users from clicking on other layers

Hi

I bet there are a few tricks for this one.

I have about 10 layers. As a user clicks on one layer another appears, to show a sequence of events. So I need all layers to show. I'm using hotspots to trigger and show the next layer, that way the user can click approximately on a complex object.

The problem I'm having is that the older layers can still activate. So occasionally when I'm testing, the whole sequence grinds to a halt as an old layer is accidentally active on another part of the slide.

The only solution I have so far is to do away with the discreet hotspots and have one for the whole slide on each layer. But this reduces the user driven effect significantly.

Oh, another one would be to include all objects in the sequence in subsequent layers too. Would pausing each layer's timeline work too?

Is there another more elegant solution?
