If you use Safari in Mac OS 10.3, you probably have noticed the built-in popup blocking feature. This is very evident when trying to view bills, faculty evaluations, etc. in MUOnline - they will not display (a blank white box tends to come up and then disappear, but not always.) The process to allow popups to display is relatively straightforward and just requires four steps, listed below:

1. Open Safari.
2. Click on the Safari menu.
3. The third option down will say Block Pop-up windows. Look to see if there is a checkmark to the left of this.
4. If there is a checkmark, click on Block Pop-up windows. This will disable the feature. (If there is no checkmark, the popup blocker is already disabled.)

This should stop you from having problems using MUOnline and other websites that require popups.
