Scrollpane not loading content... filled white

I wrote a thread a few weeks ago with the same problem, and have been searching the forums, but to no avail!

I have a few scrollpanes loading mc’s, and have set the actionscript to export on frame 2, while keeping all my exported mc’s on frame 3 (outside of the stage), and frame 4 has all my main contents. The only way the panes work is if I export the actionscript on frame 1, which is very inconvenient due to the extra loading time for the classes. Is there any workaround?
Please help!!!
