Netscape Issues.
If you use any lines similar to:
[script language="JavaScript" SRC="trigger.js"][/SCRIPT]
[script language="JavaScript" SRC="MTS3Interface.js"][/SCRIPT]
...then you need to be aware that you must have that file present in the location indicated. If not, Netscape will crash. To the user, this makes it look like your content caused the crash. The problem lies with Netscape, but the user is unaware of this. So make sure that the file is present.
