If the window screen does not display, confirm the following. 
• The screen switching device for the window screen to be used is set in the screen design software.
• The value of the screen switching device is correct.

The screen corresponding to the value stored in [Screen Switching Device] is displayed as a window screen (overlap window, superimpose window, or dialog window). 
When the value of the screen switching device for the window screen to be used is 0, the window screen is closed.

◆ For GT Designer3 (GOT2000) Version 1
