A friend of mine has an ADSL account with BT/Yahoo here in the UK. For some reason BT/Yahoo feel compelled to supply (nay insist upon) a customised version of I.E. as the browser for their customers. Okay so first things first: why choose I.E.? If you are thinking it's for that old chestnut of greater compatibility with a higher number of websites, think again. That argument would work if your customised browser was simply IE rebadged and to all intents and purposes presented as IE. This monstrosity doesn't -- it presents as a BT/Yahoo browser based upon IE. Thus some of the IE compatibility works and some doesn't. But there's more -- much more.
