Here is a screenshot: http://img.photobucket.com/albums/v136/jendreams5/ScreenShot2013-09-15at32502PM.png
That was taken after I had removed my squad from the island (Flight Squad, as is indicated by my active squad tab in the top left-hand corner), and tried to click on an empty area on the edge of the island (the one I had just left, because I knew I had been there before). The screenshot doesn't capture my pointer/mouse, but clicking on any empty area does nothing to my options to move. This has happened multiple times regardless of where I try to move to or land on the island. I am using Safari version 6.0.5 on Mac OS X 10.8.4. Thank you for your help!
EDIT:
Here is another screenshot: http://img.photobucket.com/albums/v136/jendreams5/ScreenShot2013-09-15at33009PM.png
That one was taken when I clicked on someone on the outer perimeter of the island, and was given the option to battle. If I battle this player and win, I will take their spot, but I will not be able to move from that spot unless I can battle someone else adjacent to my area.
