Hi, I am Peter
Anything done with the overlays panel is only supported in DPS or AEM Mobile.
If your goal is Publish Online close that panel and don't ever open it again. Also, close the SWF preview window and don't ever open that again, either.
Now, if you can describe the issues with the animations and what you mean by the overlap you seem to be having along with screenshots, someone here might be able to help.
For scrollable content use this handy too: Universal Scrolling Frames | Ajar Productions
