The point is, I started 3.6.7 in combination withe 21/09. So there are 2 tings different. In the former setup I didn't have this problem( 3.6.5 and 19/09)
The VP files are the 3.6.6 onse from the open Source website. Plus several upgrades like the 3D shockwave , high poly orion) These gave me no problems before.
This is the first time, after using many builds, that i have troubles when using OpenGL.
I have not tried an other pilot. I will try later on.
