Update 4 is not publishing correctly for iPhone HTML5 display(?)

I just created and published my first course with Update 4.  I published for HTML5 without the mobile player.  The course works great in IE10/Chrome on a PC (Win 7) and works great on my iPad (iOS 7).  However, when I view the course on my iPhone (iOS 6), half of the screen is cutoff (see attachment).  I thought this was maybe me, so I went back to a previously published course which still displays fine.  I republished the .story file untouched with Update 4 and loaded it to my LMS.  This course also is cut in half.  So it seems to be something in Update 4????  I also tried changing multiple settings in the Player too and that did not solve the issue.  HELP!!!!
