When is a GIF Finished Playing?

Guys - thanks for this input.  I'm going to experiment with 'rolling my 
own' GIF player as suggested.  I guess I was just looking for an easy 
way out.  There's a lot of time based events happening simultaneously in 
the project I'm working on so I'm already relying heavily on 'send' 
commands to get around Livecode's single thread environment.  I also 
have code which detects when end users interrupt a sequence of time 
based events so there's one more thing to code for, but it shouldn't be 
too hard.

Thanks again,

Ray
