Answers to your questions:
Can’t have more than one IE6 window open, otherwise it goes slow.
‘It’ being the entire system – all user accounts.
You don’t get any error messages, do you?
No, no error messages of any kind – except for when I close the IE window (the only area of the screen that doesn’t hourglass) – then I get the usual “this application has stopped working” and “do you want to send an error report?” popups.
And for general reports: have you looked in the Event Viewer?
I think I must be like the auto mechanic who drives a jalopy – I pay so much attention to everyone else’s systems that I sometimes slack off mentally with my own. I don’t usually check the Event Viewer on my own system, but there ARE several Application hang errors present. I “sent one of them to Microsoft” – if that’s where they go. I don’t know if anybody wants to see one of them here, but I’ll include it at the bottom of my post.
Do you have all other security updates for XP and IE prior to the November batch?
Yes.
Has Internet Explorer 6 been stable and working all the time until this?
Yes
Have you checked the PC with the latest definitions for your anti-virus and anti-spyware software? [/b]
Yes – I currently use Avast! antivirus and a combination of Malwarebytes and Spybot malware detectors. AdAware too, occasionally.
