Hello,
I am posting a simplified version of my code to demonstrate the problem I am having.
If I click on a menu item, one window opens.
Then, if I click on another menu item, TWO window open. Following clicks cause two windows to open.
I only want one window to open at a time.
If I remove ajax, it works fine.
It seems like Sys.Application.add_load(OpenWindow1) is not being rendered on the page. Not sure why.
Please help.
Thanks,
Simone

Hi Simone,
All the best,

The problem comes from the fact that you attach the load handler every time but you never remove it. Would you pease test with the following modification:
<script type="text/javascript"> function OpenWindow1() {Sys.Application.remove_load(OpenWindow1); var oWnd = radopen("WebForm1.aspx", "wndWebForm1"); } function OpenWindow2() { Sys.Application.remove_load(OpenWindow2); var oWnd = radopen("WebForm2.aspx", "wndWebForm2"); } </script>Svetlina Anati
