Thanks Lucky Jack you are correct. They game plays fine with little CPU usage overall, ~40% but freezes and spikes ONLY when I try to use the 3rd mouse button on the laptop trackpad.
DARCA, you miss my point as a external mouse is not desired. I play with a high end laptop so I can be mobile, like sitting on the couch and trying to use an external mouse there is just not possible.
GalCiv 1 and 2 worked just fine with a laptop trackpad, not sure why 3 can't make the grade.
