Hello,

We have the following issue with both our code and the DXEngine samples: if one clicks on a DXViewportView after its containing window has been minizied then maximized, that viewport is no longer displayed.

To reproduce:
- launch the DXEngine samples that come with the commercial version
- select the "frustum culling" samplen play around with the mouse a bit
- minimized the main window, then maximized it
- click on the viewport to try and rotate it => everything dissapears...

Any hint? This is a blocking issue for us.

Best Regards,
Xav
