WVISIBLE Help Excerpt explaining the WindowName parameter
You can also include the empty string in WindowName to specify the main Visual FoxPro window.

>As you probably, Larry, VFP internally manages it's windows via what's referred to as a whandle. It's like a window handle. The foxtools library, in fact, includes a function (_WhTohWnd()) to translate these values.

Doing some digging with Spy++ (what a great tool!!!). The _WFindTitl("") returns a reference to some invisible window created by VFP but operating outside of the IDE environment. The window isn't owned by anything and it is not a child of anything but it is associated with one of VFP's threads. Maybe its asscoaited with a cleanup/garbage collection thread or something.
