Found the solution
When you've ploughed though this
discussion, you should end up at this
MS FixIt
Forget all the babble about Google's Chrome, its a problem with that's arond for years. After applying the FixIt (otherwise known as a patch) I had to reinstate Firefox as my default browser.
Its a registry change, you can do it by IE Options or via regedit if you're that way inclined, full details are in kb article containing the FixIt.
So MS now send Mike the Mechanic to FixIt. It is said by some that computers are bad for children, but I think they are bad for adults because MS treats them like children. Its the same mentality that gave us UAC whose sole purpose is to relieve the user of the responsibility of behaving like a grown up. Who remembers Bob (not Bob the Builder, but Gates' BoB)
