wxScrolledWindow and Sizer

[B. Carrupt]

Hi,

I have a wxScrolledWindow into another wxScrolledWindow. When I set the scroll rate to use scroll bars in the inner wxScrolledWindow, my scrolled window is resized only when I make the frame bigger, not when I make it smaller.

Here is a complete sample that should compile. 

Note that it works perfectly on version 2.4 compiled with gtk under Fedora Core 2.

I use the version 2.8.3 on Fedora Core 6 and I compiled wx with gtk2.

Thanks for your help.

Blaise
