I am having an intermittant problem with the mouse controlling the knobs and switches while in virtual cockpit view in 737NGX. It works when I initially enter the cockpit but after scrolling around the cockpit with the hat on my joystick and using the pull down menues I am unable to use the mouse. I'm not really sure what causes it, but it has happened numerous times. If I switch to 2D pilot or 3D co-pilot it works, but will not work again in Pilots view 3D.
I'm running an Nvidia card with the latest drivers, 8 GB Ram, Windows 7, 64 bit
