Pop up window problem on different broswers! please help!

Hi, hope someone can help!

I have built a flash mx site on a mac.

It is in testing now, originally I had a problem with the pop up windows on the portfolio section of the site not working on Internet explorer 6 on a Pc but they worked fine on Netscape. I was originally publishing the swf using dreamweaver 3, so i just thought on the off chance i’d use dreamweaver 4 to publish the site and pop up and maybe that might fix it - it did fix my internet explorer problem but then it failed to work on Netscape and xp.

Does anyone know what the problem is??

This is a link to the site;

Also someone mentioned to me that some pop ups are blocked - can you block them and unblock them on your personal browser settings? How does that work?

I’d really appreciate any help as i’m baffled! Cheers
