When you first double click the icon and the first splash screen comes up, try clicking video settings there, and at the top it will say Select Video Card at the top with a selectable field which shows Video card and displays. If you select your "non laptop" monitor there, do you get the same thing?
Only reason I know it is there is the reboot gremlin got me...went to bed all is good. Woke up and when I fired up AHIII, it showed on my small monitor. Couldn't figure it out as Primary screen wasn't changing things for me.....
