Crash on minimize?

Hi,

When I minimize my Windows.Forms window containing a Mogre render window, the application crashes with an unspecific runtime error. According to the log, Ogre seems to unload itself as soon as I minimize the window.

This is my Ogre log:

Please help.

Try not to render when the window is minimized.
Or use OpenGL.
