*	Sara Cowles/Elverse Jordan (rmgconnect) - Changes on 12/10/05
*	Added isOver flag (line 17) to eliminate JavaScript errors produced when a user moused out of navigation
*	image before mousing in (on initial load).
*	Flag set in gsnOver, checked in gsnOut.
*	Problems in Firefox noted - commented out superfluous lines in gsnInit that seemed to solve the problem.
