+                This test is for testing the bounds of a multimonitor system.
+                You will see a Frame with several buttons: one marked 'Fill
+                This Screen' and an additional button for each display on your system.
+
+                First, drag the Frame onto each display and click the
+                'Fill This Screen' button.
+
+                The Frame should resize to take up the entire display area
+                of the screen it is on, and the button text changes to say,
+                'Get Smaller'.
+
+                Click the button again to restore the Frame.
+
+                Next, use the 'Move to screen' buttons to move the Frame to
+                each display and again click the 'Fill This Screen' button.
+
+                If the number of 'Move to Screen' buttons is not equals to
+                the number of screens on your system, the test fails.
+
+                If the Frame always correctly resizes to take up ONLY the
+                entire screen it is on (and not a different screen, or all
+                screens), the test passes else it fails.""";
