The "Close" menu item on the file menu has a typo. There is an extraneous period before the word Close. i.e., it's showing ".Close" rather than "Close" Should be a trivial fix! (My favorite kind)
The "." before a menu time means that selection is not working yet. This is not a bug...just what developers are doing to let us know it does not work yet. Thanks though! Keep sending those bugs!
