I think the problem with the mouse is still there.
I got it last weekend while playing combined arms.
Ground Units uses only the stick (imho not a good choice).
So i edited the default.lua for the mouse in Mods\tech\CombinedArms\Input\mouse and delete the lua in the savegame folder (to force a creation).
The result was double entries for rotate turet and elevation. Two lines for the stick and two lines for the mouse. That cant be good. So, if i start the ca, jump to a tank/plane, i can use the mouse. But after testusing the stick, the mouse is gone. This is bad.
Next bad thing, sometimes mouse is inverted, somtimes not when starting a mission. I dont know why. Must be a software bug.
If i play CA, i would use the mouse for the map and vehicles and maybe the stick for the planes (never tried). Both (stick and mouse) have to work parallel.
Is there a way to fix this?
