When you zoom in to a detail of your application window, the thumbnails window shows you the relationship of the detail to the whole application.
The Thumbnails window gives you both an overview and a detail of the development area.
Show or hide the Thumbnails window by selecting the Thumbnails button.
A red rectangle is the boundary of the zoomed area within a window.

-
Drag the red rectangle to show a different part of the window.
-
Select on a different area of the window to move the rectangle to that area.
-
Resize the rectangle to change the zoom level of the display area.
The thumbnail view shows a white rectangle for objects that you cannot zoom in on, such as an ActiveX control.
If you have specified an application target resolution that is different from your screen resolution, the boundary canvas outlining your specified target resolution dimensions will also appear in the thumbnail view.

Note: Application windows exceeding the dimensions of the target resolution boundary will still appear in the thumbnail view as seen in the example above.
