Weird problem with pop-up window (a new one)

Wuzzap.

I´ve been messing around with the “Launching a Centered Pop-Up Window (http://www.kirupa.com/developer/mx/centered_popup.htm)” tutorial, and have been quite successfull to some extent, but now I have a problem.

Some users have brought to my attention the fact that the pop-up does not work on Internet Explorer. I´ve not noticed it ´cause I use Firefox, and it works smoothly in it.

I gave it a try and noticed that, if you load the movie directly from the normal link: http://noblest1.vila.bol.com.br/ it works ok, both on IE and Firefox, but if you reach the site using the address from .cjb.net (the one the users were accessing): [url=“http://noblest.cjb.net”]http://noblest.cjb.net the pop-up just work on Firefox, but not on IE.

Check it out, try using the buttons in those links:
(In the main animation choose the button “fotos”, then any of the buttons inside the loaded movie clip, and click a thumbnail - it should open a pop-up)

http://noblest1.vila.bol.com.br/
and
http://noblest.cjb.net

Weird uhn?? Both link to the same address, but using cjb.net prevent the pop-up from opening. Anyone have any idea of what I should do if I were to keep using the cjb.net service?

Thanks in advance.
