Here is some text. The popup should be in red. Click on some text not in the popup to make the popup go away. Now use the View pull down menu and choose Source. The expected behavior is for a source window to appear -- no source window will appear.
Similarly, if you use the View pull down menu and choose Text Size and choose a size, the text will not change size. If you look at the "Text Size" menu again, you will see that the previous setting was not changed.
