/**
 * @test
 * @bug 6614214
 * @summary Verifies that we enter the fs mode on the correct screen.
 * Here is how to test: start the test on on a multi-screen system.
 * Verify that the display is correctly tracked by dragging the frame back
 * and forth between screens. Then verify that the correct device enters
 * the full-screen mode - when "Enter FS mode" is pressed it should enter on
 * the device where the frame is.
 *
 * Then change the order of the monitors in the DisplayProperties dialog,
 * (while the app is running) and see that it still works.
 * Restart the app, verify again.
 *
 * Now change the primary monitor on the system and verify with the
 * app running, as well as after restarting it that we still enter the
 * fs mode on the right device.
