If this is not the problem check that you have all your pop up blockers disabled to test if this is causing the problem. Also check if you have Norton's Internet Security on your system.

If you have Nortons Internet Security:

4. Once added, on the global settings tab, go to "Information about your browser" and set it to "permit"
5. Go to "Information about visited sites" and set it to "Permit"
6. Also check what Pop UP blockers you are running and add uvlink.uvu.edu to the allowed sites
