I have a web page that is split into 2 frames with a java.awt.List in the left frame and other selected applets in the right frame. The List works as a selection for which applet gets loaded into the right frame. Sounds pretty simple right?

Well my issue is that when I click on the List a lot without allowing the applets in the right frame to completely load all the way, I get errors in Internet Explorer that causes a crash (That friendly little box that says: something has occured to cause Internet Explorer to fail, do you wish to send a report to Microsoft?).

Here's some of the errors in the Java Console...

java.lang.NullPointerException

I did some research on the net and found that these are AFC objects which I am not even using (I'm using AWT). What could be going on and is there any way of debugging stuff like this.
