How to move all the application windows to the MBP's main LCD?

[hajime]

Hello. I was using the MBP with an external LCD screen last night. I watched TV on the external LCD while having another application displayed on the MBP's screen. The main desktop was set up in a way that whenever the MBP is connected to the external monitor, the main desktop is displayed on the large external monitor. Now I am on the street. Even I rebooted the Mac, the application is automatically opened in another display which I cannot see. I know this because when I clicked minimizing the window on the menu bar, I saw the application window minimizing from the right edge of the MBP's screen to the dock. I went to system environment->display. There are two options at the bottom. One for collecting all the windows and the other is for searching for display. I have tried both options but the application window does not move to the MBP's LCD. What can I do to bring the application window back to the MBP screen while on the road? The application is opened but I cannot see it under Space. Using the trick of lowering the MBP's LCD resolution and then increasing it again does not work. (It worked yesterday when a very small part of the application window appeared at the edge of the MBP's screen.) I am using MAc OS X 10.6.8. Thanks.

Apple menu > System Preferences > Displays > Arrangement tab, choose Mirror Displays. The opened app should now be seen on your MBP lcd screen.

Thanks. Is the problem due to Mac OS or the application?

A well-written application will not not draw a window off the active monitor(s).

(Still there are lots of applications that do this.)

Hello. I am on the road and have the same problem again. When I read your reply (at home), I could see the "Arrangement tab". When the MBP is on the road, I only see the "Display" and "Color" tabs.

Before I left home, I intentionally moved the application window from the external monitor desktop to the desktop on the MBP's LCD. This problem should not happen again. However, when I just turned on my MBP on the road, the application window hides to the invisible desktop again. Rebooting the machine does not help...
