Not finding an explanation with the patch, and not being "the sharpest tool in the shed", it took me a while to find out how the "mouse look" function is turned on in OIF.
(Thanks to actiontrip.com for providing the answer.)
Now if only I can figure out how to program my CH Products
joystick/Control Manager software to create an on/off switch for it so that I don't have to hold it down. Suggestions/tips anyone?
