Comment 19 for bug 153045

In fact, there is a method to close the two blank windows. First , move your
mouse to the position of "File" on the menu-bar. There nothing there, but
you know that is the position for "File". Although nothing is there, you can
click it and bring up the File Menu. Then by choosing "Close", you can close
the blank windows. As far as I know, this method can close the two blank
windows and does not affect the normal window.

But the two-blank-windows problem is still very annoying. I wish someone
could come up with a real solution.
