When you use one of VisIt's menus to activate another VisIt postable window, such as a plot attributes window, the window manager is free to show the window wherever it likes. When you are using VisIt on a large display where the windows might pop up very far away from VisIt's Main Window, it is sometimes convenient to make sure that windows that can be posted to the Notepad area are initially posted to the Notepad area instead of popping up wherever the window manager puts them. To make windows post to the Notepad area by default when they are shown, click the Post windows when shown check box.
