   Image disapperas after pressing Ctrl+Alt+Del
  I have Win32 Direct3D application which works with DirectX 9 SDK. When this application is running, I press Ctrl+Alt+Del, dialog "Lock Computer - Restart - ..." appears, then I press Esc. After this, Direct3D image disappears, and Win32 window used for rendering becomes transparent. How can I prevent this?BTW, this effect can be easily reproduced with ant Direct3D SDK tutorial, for example, Direct3D\Tutorials\Tut02_Vertices.   
  Are you catching the lose of the device and resetting it?   ;  No. How can I do this?   ;  Here it is the reference page from the MSDN :http://msdn.microsoft.com/en-us/library/bb174717(VS.85).aspxTake a look, its pretty simple.   ;  Thank you, I will try this.   ;  There is also the DirectX Forum FAQ :)   ;  While you're at it, I'd enable the debug runtimes - they'll be screaming errors at you which you just can't see.   ;  Thank you, I hope to solve my problem using this information.
