Resolution:

There are two suggested workarounds

1. Uninstall version 1.5.0_06 and revert back to version 1.5.0_04 which can be found at www.java.com.
2. Choose to always trust Java certificates for WebCT and restart the browser.  Sample steps:

1. Log in to WebCT. After a few moments, one or more "Warning - Security" pop-up windows display with the message "The application's digital signature has been verified. Do you want to run the application?"
2. Make sure the option to "Always trust content from this publisher" is selected.
3. Click Run. The browser freezes.
4. Manually shut down the browser through Task Manager.
5. Restart the browser, and log into WebCT. The "Warning - Security" pop-up window does not display. Proceed to access WebCT normally.

It is possible that you may have Sun Java installed on your machine but the Windows version of Java has been set as the default rather than the Sun Java version.  The following instructions describe how to make Sun Java the default Java application for your machine.

1. On the menu bar, select Tools then Internet Options to open the Internet Options panel.
2. On the Internet Options panel, open the Advanced tab.
3. On the Advanced tab, scroll down and find the Java (Sun) top-level heading in the list. Make sure that the Use Java 2 ... option under it is enabled.
4. Look directly below the Java (Sun) heading for the top-level heading Microsoft VM and de-select all options under this heading.
5. Select the OK button to close the Internet Options panel.
6. From the Windows Control Panel, open the Java Plug-in control panel.
