What are the symptoms? Many different things are not working correctly. For example, if I bring up MS Outlook, nothing at all shows up in the main window. The folders are displayed, but that is it. I don't see any of the mail, preview pane, etc. And
if I click on File to try and do something, Outlook immediately closes.
Then there's IE. All of the links in my Favorites don't work. When I get into IE it tells me that I've got to install things like Real Player, even though I already have it installed. It tells me I need to install Java, even though I already have it.
And links don't seen to work half of the time. And further more it looses its configuration from one invocation to the next. For example, it never comes up on my start page, and when I reset it, if I close IE and then get back into it, it has lost it.
Then there is Windows Live Messenger. It never remembers my email address, password, etc. I enter my credentials and it never logs into the Live Messenger server.
Then there is just logging in. It is complaining that all sorts of things which I've installed, are not there. Yep, things have gotten suddenly very strange, very difficult and basically impossible to work with.
