Game Explorer bug

After I enter a series of moves in Game Explorer and then click on a game, I like to go back to Game Explorer to explore the same line.  When I use the "back" function on the browser (both Chrome and Firefox exhibit this) the line which I was exploring in Game Explorer is not displayed--but it is remembered.  A fresh board is displayed.  When I enter a move on the fresh board an error message pops up because the Game Explorer is still storing the line I was exploring but not displaying it.  I would like Game Explorer to display the line it is rightfully remembering.  When you fix this bug, please do not make Game Explorer reset when I return to it.  I would like Game Explorer to remember the line (as it is doing now) and to display it and the appropriate position and to not give any error message pop-ups.

I've experienced this as well.
