Buttons issue for left-handed players

[oxis]

Hi,

I'm left-handed player. In windows setup i've got swaped mouse buttons (so I clik/open/drag/etc. stuff with right button not with the left one as right-handed users do). The problem starts when I lunch King's Bounty. As I have buttons changed (in windows) I should move horse with right button and rotate cammera with left one. But that doesen't work like that. Instead left mouse button does nothing and with right one I move the character and rotate camera SIMULTANIOUSLY!!!

Is there any solution to make these buttons work properly? For ex. some game files modifications or maybe a patch??
