Thanks for the replies. I am pleased to see that this is still one of
the, if not the, friendliest newsgroups online.
I tried Mikes suggestion but the small additional polyline also waited
until after the forty clicks to be drawn and then with the second
marker this line was drawn straight away and the others also
correctly, ie after each click as expected.
I decided not to investigate this further for now as I only included
the alert() to slow everything down to see if the other parts were
working. So I have tried using setTimeout to slow things down as
suggested by Larry but with this only the last polyline is drawn and
the other 39 are not. Here is the change I have made (2nd line):
myLine = new GPolyline([marker.getPoint(), point]);
window.setTimeout("map.addOverlay(myLine)",100); //just to
slow it down to find problem
var percentDone=100*mark/diskm;
I think I must be missing something elementary here. Your help would
be appreciated.
Regards,
Steve
