Hi Eric,

Thanks for the heads up. Loved your stack.

I was puzzled that you weren't getting the static 
that I get when the thumbposition of the 
scrollbar is set with the update.

Turns out that my scrollbar has a scrollbarDrag 
handler which sets the currentTime of the player. 
(I want to be able to drag the thumb to any point 
along the bar. This allows me to choose the 
starting point with the slider.)

What I needed was a way to avoid the execution of 
the scrollbar handler when the thumbposition was 
moved by an external handler, but to allow the 
script when the thumb was dragged. That can be 
done with the same device one uses in a mouseMove 
handler. I added a mouseDown handler in the 
scrollbar which puts  a value into the variable 
myName and then exiting the scrollBarDrag handler 
if myName is empty.

Thanks again,

Jim
