Resurrecting an old thread..
It seems that this solution does not return events on objects within
frames in webpages eg . if you go to www.andersondirect.com - the page
is composed of three frames called as topFrame main and address. Now
when I click on say 'Select a Vehicle' which is within main - I do not
get any Onclick event. I also do not get an OnMousemove event if I move
the mouse. However, I do get on Mousemove event on a tag called as
frameset (which is part of the top page).
How does one get events from the frames then?
As always thanks a lot.
