It seems that when I use -opengl and mouse look is enabled in the latest Vavoom, all mouse movement is interpreted as "up and to the left" and I end up spinning around staring at the ceiling. When run without -opengl, mouse operation is normal. Mouse sensitivity and "inver mouse" have the expected effects. I'm afraid I don't know enough about Vavoom to troubleshoot this (does Vavoom still use Allegro for mouse input with -opengl?).
Vavoom version: 1.16.1
OpenGL: NVIDIA 6629 (GLX 1.3)
OS: SuSE Linux 9.2
I would appreciate any suggestions-I was looking forward to playing Heretic again!
