Attached is a diff which demonstrates this problem against the auidemo.
All it really does is shrink down the width of the Tree Pane on the
left hand side. 

When built against 3.3.1, it makes no difference however with 3.2.7 you
can see the window width has been shrunk (not sure if you can actually
apply the patch directly to the 3.2 sample as there have been quite a
few changes however it's a tiny change so easy enough to do by hand).

I had a peruse of the perspective classes you directed me at yesterday,
including wxAuiSerializer however I couldn't see anything obvious in
the wxAuiPaneLayoutInfo structure which would be used to set the size
of the pane - unless it's the dock_size attribute from
wxAuiDockLayoutInfo.

Rgs,

Jon.
