[Golist] SkipTo question

[Moses Gunesch]

Hey there James, thanks for your email.

You're right, that seems broken. Maybe try setting a temp var like,  
var base:Number = (_useFrames ? _framesBase : 0); and using that var  
instead of _framesBase in that (time < _framesBase) block.

Let me know if that helps, we can integrate it.

Also -- I was working on a version that eliminates framesBase  
altogether, to reduce clutter. Hopefully will have time to return to  
that soon!
