Most modern web browsers have a built in functionality that blocks all pop-up windows.
The University of Utah uses pop-up windows for many of our www applications. As a result, you need to specifically allow pop-ups from the utah.edu domain in your web browser.
A guide has been created at here that shows you how to do this in Microsoft Internet Explorer for Windows XP SP2.
Please contact your LAN manager for specific information on how to allow utah.edu domain pop-ups for your specific platform/browser.
