I have many websites each using picture enlargements utilising the extension "Fever Picture Window".

This is quick and eay to use so I have over a thousand instances in clients sites. With the introduction of XP SP2, it is treated as an unwanted pop-up and blocked in IE.

Has anyone else come accross this and maybe found a fix.

SP2 treats every popup as unwanted. Grrr, the world should use Opera anyways ;-) Otherwise, you can provide instructions to disable for the user, let them know that the popups are safe and how to enable them, or just not use popups. Sorry and good luck!

A way round SP2 pop-up blocker is to hold down ctrl when you want to click on a link that opens in a new window
