Thanks Robert.
This is what it looked like before I added my widget to the screen.
We didn't want the "My Location" widget, so I just made it visible: false and it disappears.
And then I moved my widget into the void left by the "my Location" widget. But maybe that's the issue, that just because "My Location Widget" isn't visible, it's still there? But still, even if I move my widget down and make it the bottom widget, it still "pops off" when resizing the browser.
