OpenGL problems with Comodo Firewall 5

Recently upgraded from CFP 3 to Comodo Firewall 5. Most things are working, but all OpenGL video goes into “software emulation mode” now. It’s easiest to check with Google Earth (DirectX mode works, but not OpenGL).

Comodo version: 5.0.163652.1142
O/S: XP SP2 (x64)
Video: Nvidia Quadro FX 3700, driver version 190.38
