I will give that a try tomorrow for you. In the mean time I figured out one thing.
On my display settings (right click desktop, properties, settings tab), if I change which monitor is my primary monitor, then the main tourney screen will show up on that screen (and I can move the settings screen to the other). So, I can manage where the tourney screen is by changing which monitor is my primary monitor.
But, again, when I click on "move to extended monitor" on the TD preferences tab for extended monitor, the main screen disappears.
One goofy side effect of this is that if the main tourney screen is gone and I then close TD settings window, it appears as if TD is frozen because the program icon is still on the bottom of the screen, but if I click on it to "restore" the program, it won't do that. Of course, if I hit "esc", it brings back the settings screen.
But, what I find interesting about this is that the first time I did it, I thought that TD had frozen, so I did a ctrl-alt-del to end the program, and TD didn't show up on the application list (?).
