Frequently when I click on a hyperlink, the new page
opens but with a superimposed Yes/No prompt: A runtime
error has occurred. Line Number: Error 'null' is null and
not an object. Do you wish to debug?

Hi,
Most of the time this is just errors on the web site ..... not your end.
However some ad-blocking apps will cause this (script error) when the ad or
banner fails to display.

Internet Options | Advanced
Select: "Disable script debugging"
Uncheck: "Display a notification about every script error", click Apply\Ok

Verify these Registry entries exist and are correct:

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"Disable Script Debugger"="yes"
"Error Dlg Details Pane Open"="yes"
"Error Dlg Displayed On Every Error"="no"
"NoJITSetup"=dword:00000000
"NoWebJITSetup"=dword:00000001

Note: always Export before editing .....
[or]
Download the latest version of Windows Script 5.6 for XP\2K
http://www.microsoft.com/downloads/d...DisplayLang=en

Try installing that and see if it helps with your problem.
