Blocking a pop up in an enterprise application

I have researched the postings on pop up blockers and can't find this problem. It's the opposite of most of the postings since I am getting blocked and don't want to. It doesn't happen in IE or web pop ups but is happening on our internal network on our business software application. When I try to pull up a spooled report the report appears to get blocked by some kind of pop up blocker. I have turned the IE pop up blocker completely off but it doesn't help. Is there some other pop up blocking function that isn't in IE? I am running XP with SP2

 

How did you turn off the IE popup blocker, did you turn it off from the Tools menu? SP2 adds a popup blocker but it's simple to turn it off. If you've already done this please disregard this reply
