UI Nits: enlarge Aerolab Crr box to fit the allowed 6 decimal places
Minor focus/highlight fixups Linux

Search box gets a focus and the calendar highlighting uses
the default palette highlight -- only good for new installs
or if the user resets their colors but at least it now does
the right thing.

Need to test and fixup on Mac and Windows.
Color fixups for Windows

.. tested on Windows 8.
.. still needs foxus rectangle on the search box
   in Mac to be drawn properly.
