When I click Start>Microsoft Update, it should launch IE and run the update check, but just as IE appears in the taskbar it disappears. I normally use Firefox browser, and only have IE for windows and security updates. This isn't the only problem I've been having with IE either, and for the past year or so when it is started it appears minimised in the taskbar by default and only opens when I right click mazimise. When I try and "restore down" so the window isn't maximised to full screen, it just minimises to the taskbar again. Is there some way to repair IE by cleaning it completely from the machine and using my windows 2000 CD to replace it?
