New mouse, weird IL-2 thing

[IceFire]

Hey folks,

I'm wondering if anyone might have some insight here. I used to have a Logitech MX500 mouse from ages ago. I decided to do a little upgrading and I've just bought a Logitech G500. On the outside the mouse isn't all that different and I love the design. In windows and everywhere else the mouse is absolutely brilliant (adjustable sensitivity, weighting, etc.). But IL-2 is a weird case... in the menus and more importantly in the mission builder the pointer precision is poor and it takes a lot of movement to get the pointer to move at all.

Very awkward.

Any thoughts as to why this might be?
