I've seen it reported before , but no solutions. I have two computers, both having Galciv 2 loaded, one having a Logitech MX1000 cordless laser mouse, the other having a corded MX510 optical mouse. The first uses setpoint software, the other uses mouseware. In both cases, if at any time during the life of the mouse, I reset the function of the middle button (for example, to play BF2 or something), and then I reset it back to default, I completely lose the rotational fuction of the depressed middle mouse button. I can't get it back. VERY frustrating. I can't build my ships without the rotational function of the middle mouse button.
I use the shipbuilder alot--or, I used to, before this happened. Help! This is a game killing bug for me, and I don't anticipate being able to order expansions etc if I can't get it to work, since it ruins my experience completely.
