If a 4D Write area is less than 170 pixels wide by 80 pixels tall, the 4D Write area becomes a button. By default the button is titled, "Click here to open 4D Write area."
You can change this default title by using the command, "WR SET AREA PROPERTY" like this:
WR SET AREA PROPERTY (Area;wr minimized button title ;1;"My Custom Title")
