When viewing mail suddenly no longer have soft buttons at bottom to reply move and especially delete emails When viewing mail suddenly no longer have soft buttons at bottom to reply move and especially delete emails

I sudeenly no longer have soft buttons at the bottom of emails when I read them that allow me to move, delete, reply, etc.  This may have occurred when I upgraded to 6.1.2 or it may have happened just after that.  Any idea how to get the buttons back?
