Ok, that tells me more. First of all, you have something locally that intercepts and avois the script to be processed. You need to make sure that the javascript scripts are being executed as is. This is why you are not seeing the message as a messagebox alert javascript message. See
http://www.levelextreme.com/Troubleshooting.asp. There is a section that talks about something in regards to that.
As for the message being sent, this is sent because what was suppose to be received was incomplete. So, it means that what was sent in the frameset, which was suppose to be sent back to the server has been intercepted and changed. Again, this seems to be cause by something related to the first situation, but probably different. Are you running tools like Zone Alarm, Norton Internet Security and such?
Both situations seems to happen because of an excessive amount of security in place which afferts the normal operations of Web sites.
