+            When test runs a Frame which contains a yellow button labeled
+            "Drag ME!" and a RED Panel will appear.
+
+            1. Click on the button and drag it to the red panel while holding
+               the "CTRL" key on the keyboard.
+
+            2. When the mouse enters the red panel during the drag, the panel
+               should turn yellow.
+
+                On systems that supports pictured drag, the image under the
+                drag-cursor should appear.
+                "Image under drag-cursor" is a translucent blue rectangle + red
+                circle and includes an anchor that is shifted from top-left
+                corner of the picture to inside the picture to 10pt
+                in both dimensions.
+
+                On Windows, the image under the cursor would be visible ONLY over
+                drop targets with activated extended D'n'D support.
+                It means the image may not be displayed when dragging over some
+                windows, this is not an error.
+                The image should be displayed when dragging over the red/yellow panel.
+
+            3. Release the mouse button.
+
+                The panel should turn red again and a yellow button labeled
+                "Drag ME!" should appear inside the panel. You should be able
+                to repeat this operation multiple times.
+
