This is just a quick heads up about Norton Antivirus and it's script blocking feature. I reinstalled WinXP and then installed NAV 2003 and HAL became very unstable. Also when I added additional plug-ins and various 3rd party voices especially those that use the older SAPI 4 speech engines, L&H or TruVoice as an example, there was no stoping the disaster. "Object disconnected" constant "improper shutdown" error messages, other error messages and sudden crashes, etc.
Well, I saw no notes regarding the problem here on the forum. So if anyone ever has that problem the solution appears to be to go the the exclusions menu in the Norton program and entering "*.uhp". As added security I also excluded HALassist.exe as well. I hope you have no need to ever search for this fix but at least if you do, this may be it.
