I also tried running IE as administrator. The symptom did not appear, but it also did not fix the problem, because I'm not willing to go through the pain of running IE as administrator every time.
FIXES TO MY PROBLEM -- AND I HAD A REALLY UNSTABLE SYSTEM
1) There appear to be a number of Outlook and IE toolbars that are not compatible under Vista. They've created absolute hell for me just to figure out what's wrong. Try disabling suspected toolbars for IE and Outlook and disable ActiveX plug-ins for IE. Then enable them one by one. I haven't found a problem with any Microsoft toolbars or ActiveX controls. My culprits, I believe, were Skype (a totally useless toolbar, anyway -- what were they thinking?), and LinkedIn, and some others. I was told by HP that OmniPage is a mess, too (whatever it is).
2a) I turned of McAffee Firewall, Virus, Scanner, and all the other utilities it loads (hunt through the UI, it's hard to find everywhere to turn this stuff off.) Then, go into msconfig and uncheck anything related to McAfee. Use Windows Firewall and Windows Defender instead and just forget about loading a virus scanner. I haven't found one that actually works, and I've tried the 5 or so of them recommended by Microsoft. I think (yes, I really do think this) that virus scanning is overrated. Be careful which files you open (I may regret this later, but this has been my method for 5 years now. With a firewall, I feel safe, and I have been for 5 years. No viruses on my old machine)
2b) THIS PART WAS THE KEY TO MY SOLUTION: Out of desparation I rebooted in Safe Mode, not having a clue and not planning to unload and reload drivers, etc. one by one. Was just going to see if the system worked. It did work. Perfectly. Not really a surprise.
2c) Reboot normally. I have absolutely no problems now. None. And I had big problems:
- Network wouldn't connect after coming out of sleep.
- IE routinely crashing
- Explorer hanging
- Outlook routinely crashing
- Search Indexer no longer spins up out of control and uses 50% of my processor power.
- Computer freezing. Mouse pointer, clock second hand frozen. Keyboard non-functional. Basically, no input/output from the console. Had to do a hard reset in these situations.
- Many, many other problems. By my estimation, I spent 20 to 30 hours a week over two months dealing with Vista issues. Now, I have absolutely no problem.
My symptom was continually having Outlook or IE stop responding (like, 3-5 times a day). However, I did experience a continual loop as described in some posts. Eventually they exited as long as IE or Outlook did not hang. My hanging symptom sounds somewhat like the infitnite loop referred to in these posts, so I'm posting here.
OPINION
What do you think the economic cost to the country is of having been hoodwinked into buying a beta product? The cost is in billions when you consider business sytem downtime, lost personal productivity, people yelling at each other out of aggravation, support personnel at the ends of their ropes, etc. Vista is pretty close to a train wreck, if not in it's overall performance (it's bad, but maybe not a train wreck), then in the execution of its delivery and the effect on the human beings who have to use it. HP tells me to call MS. MS tells me that yes, it's their operating system, but the OEM vendor is responsible. Would love to see some accountability on this one, but MS has to care enough to drive it.
Remember the bumper sticker that people would put on the old Bell Telephone trucks? "We don't care. We don't have to."
