BTW - your mouse cursor is only active in station services menus and maps - all other menu selections are made using keys or hats and fire buttons (depends what you set in options / controls) - defaults are Q and E to move left and right in tabs - W and S to move up and down in menus and A and D to move left and right in selections / pages - space bar for "select".
(Drove me mad at first as I was used to click-able cockpits in flight sims.)
