#7 Minor Redraw issue on Resize DockHost

[Trancart]

Hello and thanks for this nice library ;)

If i remember well ;) , i work on a quite recent CVS
Version on MSW.

I remarked that when i resize the Left Dock Window , it
seems that it redraws a part of the screen equal to two
times the width of the window.

I mean, for example i resize a window of 100 pixel
widh, it seems to redraw a 200 pixels width on screen.(
that causes some flickering in my main window which is
redrawed each 10 ms )

Hope this helps
