Just a note of caution to all you good folk out there - I use my machines for Avid video editing and multimedia stuff and recently had some problems which all led back to the title of this thread. After prolific googling, it would appear that our bright shiny new friend does indeed create problems for a number of applications, and is the first thing you should check if things go awry without good reason. Indeed, MS even provide an IE8 upgrade blocker to stop Update automatically installing it - surely yet another admission of a flawed product. Now here's the nuisance bit - assuming you've been diligent and installed SP3, and then updated to IE8, the only way you can uninstall Explorer and replace it with the previous less toublesome version is to first uninstall SP3.
After that everything works normally tho'.
