svn-2620: Assertion failed

[HaJo]

On the first run of  this new version, during the first 1-2 minutes of play,
I clicking on the "Aircraft"-button in the base, the program crashed,
and showed a messagebox with this error:

Code: [Select]

Error: MS Visual C++ Runtime Library
Assertion failed
Program: UFO.EXE
File: ../ports/win32/glw_imp.c
Line: 590
Expression err == GL_NO_ERROR

ufoconsole.log has nothing interesting:

Code: [Select]

====== UFO Initialized ======

Probably it would have been helpful, if the other clicks
on "Building", "Hire", "Research", "Buy" had also been logged...
