Compatible with 4D 2004.x

4D 2004 has introduced a new Window type that makes for a great splash screen among other ideas. Using the new Pop up window, a developer can create a unique experience for the user. Pop up windows can be closed in a variety of ways:

- A click occurs outside the window
- The background window or the MDI (Multiple Document Interface) window is moved
- The user presses the Esc key

The window cannot be resized and is displayed in front of the "parent" window. The "parent" window is still active but will no longer receive events when the pop up window is opened.
