If this configuration variable is set to 1 (on, true, yes), the Thin Client creates an invisible window after the next window is created by the COBOL application. This invisible window remains until the Thin Client shuts down. This variable must be set in the application's configuration file or in the initialization code of the application so that it is applied to the initial window created by the application.

The invisible window is needed because the GetMessage API routine behaves differently under Windows 2000 and Windows XP than in older versions of Windows. If an application has no open windows and it calls GetMessage, the focus is transferred to another application. Once transferred, the application cannot force the focus to return to the original application, even if it subsequently creates a window to receive the focus. This situation arises under the Thin Client if the COBOL application destroys all of its windows before creating a new one.

Since this variable applies to a very specific situation, the default setting for TC_CONTINUITY_WINDOW is 0 (off, false, no). You must set it explicitly if you want to use this feature.
