Hello,
My ScrollPane will not display its scrollBar if my export frame for classes is
anything but 1. However, I have to use a frame other than frame 1 so my
preloader will function correctly. Am I up a creek without a paddle here? Or
is there something I haven't thought of? Any help would be greatly appreciated
- thanks!!!

After further examination, I've figured out the solution. In order for the
scrollBar assets to appear, you must place an instance of each of your
scrollBar assets on the stage (out of the viewable stage area, of course). For
example, I placed mine on frame 5 (which also happens to be my export frame for
classes). To find them in your library, the default names for these assets
should be "HScrollBarAssets," "ScrollBarAssets," and "VScrollBarAssets." After
doing this, my preloader works like a charm, and all my scrollBar assets appear
and function correctly. I hope this helps anyone else who has encountered this
problem.

I should also point out that this example is for those who have designed
custom scrollBar assets.
