Hi skeemo, well I don't know about your problem, but I've encountered some control issues too, but for me it's the keyboard. I have a new laptop and Windows 7 installed, and some keys don't work at all, while others do the opposite of hat they're supposed to (like the yaw keys)! I must admit though, I'm not playing LB2 at the moment so it doesn't really matter... yet!
You could try going into the CA.INI file and increasing the joystick number entries that look like this...
[Joystick]
XMin=-128,XMax=127,
XDead=1000
XSat=9000,
;
YMin=-128,
YMax=127,
YDead=1000
YSat=9000,
