How to completely disable all Internet Explorer Script Error dialogs

问题

Can someone please tell me how to disable Internet Explorer Script Error - says:

An Error has occurred in the script on this page

   ...
   Error: Unspecified error
   ...

Please don't Say to Go to Tools -> I.Options -> Advanced ...turning off debugging etc etc..

I have tried all that and this popup dialog still comes up.

Some forums suggested turning off a service called: Machine Debug Manager (MDM), the problem is that I can't find this service running on my windows version. Why?

System
   Windows XP
   Professional
   Version 2002 
   Service Pack 3

There's gotta be some way to completely turn off this dialog so that it doesn't come up. I don't mind deleting the entire registry to make this stop. that's how frustrated I am with it. FYI, I get this while running automated test using selenium RC on IE6. Hope this enough info. Thanks so much

regarding MDM.exe:

From: What To Do When . . . Your Browser Displays Script Error Warnings

Some, but not all, Windows users have the Mdm.exe file on their system.
This is the Machine Debug Manager, a program installed with the Microsoft Script Editor to provide support for program debugging. Users of Microsoft Office 2000 and above will have this program on their system. It also can be downloaded from the Windows Update Web site (update.microsoft.com).

Because the Mdm.exe file can be a source of script error warnings, you can disable it to prevent seeing more unnecessary messages.
You can use the Search tool (click Start and Search) to find the Mdm.exe file.
However, a quicker method to disable this program is to open the Run dialog box (click Start and Run), type msconfig, and click OK.
This opens the System Configuration Utility dialog box.

On the Startup tab, look for the Mdm.exe file on the list.
If it’s listed, deselect the corresponding checkbox. You will then need to restart your computer.
Don’t worry if the file isn’t listed on the Startup tab. Even if the Search tool found Mdm.exe on your system, you may never need to run this program.

Note: in the same article, it is also mentioned:

When turned on, Internet Explorer’s pop-up blocker tool can be a source of script error warnings.

回答2:

For people looking for a solution for later versions of IE (I cannot verify if this works on IE6) and if the above solution is not working for you, try this:

Assuming you're running from the command line, run with -multiWindow. I had previously been running with -singlewindow which was throwing the Script Errors.

This worked for me on IE9. I have not checked IE8 yet, though.

Hope this helps :D
