Hi,
I am getting a crash when exiting my application. My guess is that parts of
the OSGText stuff gets deleted / destructed when the window is no longer
available.
Call stack appended at the end of this mail.
The debugger showed me that TextFaceFactoryBase is a Singleton and is
destructed by the call of osgExit, but it is holding a HDC variable. However
at that point the HDC as well as the OpenGL context are already destroyed.
Is there a way to destruct all the stuff manually, or is it usually better
to call osgExit before the window is lost?
Aloha, Andi

First-chance exception at 0x77b62272 in BioSG.exe: 0xC0000005: Access

Btw I guess that the living image is also part of the text environment -
otherwise I have no idea what it could be. I set all variables to 0 before
deleting the OpenGL context and also delete the scene manager.
