I'm replying to my own post. Ancestral Quest windows will not open if you are using an external monitor and have it setup as the control screen. My 23" LCD is easier to use as the control monitor, with the laptop screen being the external monitor. Easy to change back and forth in the System Preferences, Displays, and Arrangement screens. You can move the small rectangle from one screen to the other, designating one of them as the control screen.
Ancestral Quest will not run when the 23" monitor is the control monitor. It is probably running, but I can't see the screens on either monitor. Switched it back so that the laptop screen is the control screen and it works fine.
Not sure whose camp this bug is in, but it is frustrating and took a while to figure out the solution.
I can run it under either coherance or full screen Windows 7. But, not with an external control screen.
