Pop-up MADNESS

Okay. I have everything set up so a pop-up window opens when a certain button is clicked on. I also have a domain name that redirects to the server/account where the site exists. When I go straight to the site without using the domain name (http://home.cwru.edu/~rjm21/), the pop-up works. When I go to the site by typing in the domain name ([url=“http://www.sometimesi.com”]www.sometimesi.com), the pop-up doesn’t work. However, this is on my work computer; on my computer at home, it works just fine. I’ve had some friends without pop-up blockers tell me they can’t open the window.

What in the poop is with this? I am completely lost.
