But, of course, it can be you have additional security software installed that blocks this particular operation. And it might be that different versions of Windows or IE have slightly different settings. I seem to remember a version that had separate options for using scrips in IE and in other applications.

I have recently had to do a recovery on my Vista laptop with Office Pro 2003. I've had a few problems getting Outlook 2003 to work with my BTYahoo email. (I'm trying to avoid paying BT to sort me out).
Outlook sends test messages OK but doesn't pick up incoming messages from the server. When I try to access my account settings on BT Yahoo mail, I get an error message saying that the page needs Javascript to be enabled. Can anyone tell me how to do that please?
