I am finding many mouse issues with running GalCiv 3 on a laptop.
The support for the built in trackpad/mouse is limited. Specifically I keep running into issues with the middle or third mouse button functions. It will occasionally zoom in and out but usually it causes the game to consume 100% CPU and stop responding.
There is no support for rotating objects. No button combination allows for the built-in mouse to allow for rotating objects/ships.
Hope there is a plan to fix this.
