History manipulation - Way to block a page from the History?

I have a 2 frame frameset.  1 main window and a left nav window.  Upon an external event Javascript code is sent to the main frame which then runs and changes the leftnav frames page.  The problem is when the Back button is pressed the leftnav window goes back but not the main frame window.  Back has to be pressed a 2nd time in order to make the main frame go back.  I would like for the leftnav window to stay where it's at and the main frame to go back when the Back button is pressed the 1st time.

Is there a way to programmatically block the leftnav page update from going into the history?
