I have a similar problem.

I've placed it besides the textbox and related it to the text.
All is fine, but when I go to another page and return, the scrollbar just disappears.

No errors or such, it just disappears.

Anyone managed to solve this little bugger?

ps: maybe it's because I've stripped down this custom cs4 scrollbar. Going to check that...
I wonder how you solved it nayim

Well, I've added a new one and non of that was happening;
untill I began stripping it down again.

What a bummer. I don't know why adobe let us change the color of that hidious yet usefull scrollbar.

It is repulsive :):) for me so I really do want to find a way to adjust it.

And the strange thing is when you adjust the width and such in the assets library of the scroll area or scroll bar. It just jumps back when exporting.

Man man man....
