I have tried every angle of positioning I can think of but I can't seem to get the balloons to behave correctly when scrolling.
If the dialogue characters move (within the TB frame) then the balloons follow that character. [b]BUT[/] if the window scrolls the balloon follows along - until it hits the outside of the TB frame.

I have a modified TB file if you have time to look at what I am trying.

Does anyone have any experience with this?
