I have a Dell Vista laptop with mobile 945GM express chipset. I am using DX 9.
When the device is reset (for example by toggling fullscreen), lighting is lost. This happens in my game but also in some of the DirectX samples - for example when I reset device with the SkinnedMesh sample, the character then renders black. I can't see any flaw with the code and since this happens with the DX samples I thought it might be a driver bug.
What is the fix please?
