WxWidgets panels in sizers don't seem to be working

问题

I have a WxWidgets project that is setup like this:

Main Frame->Main Panel->Vertical Sizer
  ->Horizontal Sizer for a few buttons etc
  ->Horizontal Sizer that shows all the main info.
      ->In that main sizer, I have a SimpleBook
           ->The Simple book has 3 panels in it.

No matter what, the SimpleBook's visable page is under the top "few buttons" sizer.

When having a panel in a sizer, the does the panel abide by the sizer's location within window?

This looked "perfect" when the SimpleBook was a Sizer. But I'm trying to fix bugs in this stackoverflow question.

EDIT: Adding simple code. Any mistakes etc in here is simply a copy/paste error. The code compiles perfectly fine. It was hard to find all the relevant pieces to copy here.

You must create wxSimplebook pages with the book control itself as parent and not some completely different window.
