Hey guys,
Is it ok to call MessageBox with an active device and swap chain? Just by chance I forgot to rename a compiled shader file... and the following code started to crash on the MessageBox line. But if I move the MessageBox line to below the FreeDirect3D call, the message box displays fine. I'm on on an AMD card with latest drivers running a sample D3D11 application in windowed mode.

Thanks!

This crashes.

This works OK.

EDIT: After some more testing, for me, any MessageBox called after D3D11CreateDeviceAndSwapChain but before a call to CreateVertexShader crashes atidxx32. Any MessageBox after the call to CreateVertexShader doesn't crash.

Full source code crashes on line 47 of d3dapp.cpp.
