Weird... if I change the WindowProc like this :
LRESULT DHCtrl::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
	DEBUG_INFO("WindowProc:" << message);
-->	if(message == WM_ERASEBKGND)
-->		return true;
	GuiLock __;
	return DefWindowProc(hwnd, message, wParam, lParam);
}
The problem disappears. Don't know why, but that's a solution at least.

Hi,

I have to say I am now in intense period of OpenGL development. I will probably cause you some problems, right now I suppose that "picking" does not work anymore (but IMO it should have been implemented separately anyway).

Things I have changed (so far just in Win32):

There is now just single OpenGL context. That is all that is required - OpenGL can switch context between windows. So it is faster and more importantly, textures etc.. can now be shared between windows safely.

I have noticed that if OpenGL view is part of application, some things are less snappy (e.g. when Splitter is involved), so I was playing with WM_PAINT a bit.

BTW, I think that I have did the same fix as you suggest independently, so perhaps you just updated to some intermediate variant.
