I've just had a look at the Visual .Net environment and you can specify the 
backcolor of a window (and the background image) in the Designer - now, how 
this is achieved under the hood is a different matter:) The problem with 
using a class to set the background is that you can't change it during 
runtime.

Setting the background of a window does seem to crop up now and again - and 
I've been stung with it several times - so a solution would be nice - but 
how much work would be involved with the fiddling of WM_PAINT/WM_ERASEBKGND? 
Is there a risk of it breaking other things? Performance?

Cheers,
