Lotus Notes 8 – ‘A Runtime Error has occurred. Do you wish to Debug?’

I’ve had a few cases of users running into this error message in Lotus Notes 8.0.1:
 

 
The problem is tied to the embedded version of IBM’s instant messaging system Sametime, and has been reliably reproduced in any of the following conditions:
 

• Initiating a chat session
• Clicking the telephone icon
• Receiving a chat

 
According to IBM, the problem is solved by upgrading to version 8.0.2, and they also say there’s a hotfix available.
 
There is, however, a workaround, which also seems to work reliably. Here’s how to implement it:
 

1. Open Microsoft® Internet Explorer
2. Click Tools -> Internet Options -> Advanced (tab)
3. Locate the option “Disable script debugging” and put a check mark in the box
4. Locate the “Display a notification about every script error” line and remove the check mark in the box
5. Check the option “Disable Script Debugging (Other)”
