I got it working by writing a small html page with a back button and a
forward button on it and I display that above the graph in a FRAMESET.
All the graphs get sent to CNTFRAME as the target hence this name
appears in the ONCLICK definitions below. No apologies if Google
totally messes up the format of the html code below.
Now the odd thing is, if I include this html page above the graph,
then the Back button on the browser automatically starts working
properly so I don't need the little html page with the back button and
forward button. But if I don't put it there then the browser Back
button stops working again.
<!DOCTYPE HTML PUBLIC "Roland's test back/fwd button page">
<BODY BGCOLOR="#FFFFFF" TOPMARGIN="0">
<TABLE BORDER="0" WIDTH="90%" CELLPADDING="0" CELLSPACING="4">
<INPUT TYPE="BUTTON" VALUE="Go Back"
<INPUT TYPE="BUTTON" VALUE="Go Forward"
