Alert problem

Hi,
In IE when this page is loaded alert window does not pop up. Can u pls tell what could be the reason? This works well in Netscape. However when an alert box is popped up from a click event of a button it works fine.
Thx
Anu

Are you running any pop up blocker software on IE? That might be the cause of it.

Thanks. You are right
