Controls won't get resized in deep window hierarchies

We have an application with a complex hierarchy of Splitters, Pannels
and Resizable dialog-views. Recently we noticed that on 64-bit Vista
resizing the main frame would fail to resize the inner-most windows or
controls.

A bit of research got me to this:

http://blogs.msdn.com/alejacma/archive/2008/11/20/controls-won-t-get-resized-once-the-nesting-hierarchy-of-windows-exceeds-a-certain-depth-x64.aspx

Turns out that recursive calls WM_SIZE must not exceed a certain depth
which on x64 is not very large.

It's a known bug. An awful one. Yet another reason to make me want to
switch to a HWND-free framework, and to never have to deal with the
problems and limitations Microsoft has in Windows' controls.

Anyway, the question is now: what to do? Anybody had encountered this
problem before? Suggestions of a workaround? I can't exactly change my
hierarchy thus I need a way to deliver the WM_SIZE messages
non-recursively. But they are triggered by main frame resizes and the
recursive calls are in CDialogResize, Splitter and Panel. So I am at a
loss.

Any suggestions are GREATLY appreciated.

Thanks,
Cata
