IE7 compatiblity - a nightmare for developers

In fact this has started a IE7 Web Developers Nightmare. The article actually explains that most of the small company B2C sites may just fall from grace because of IE7 incompatibility. One of the coolest thing IE7 is unable to do is actually processing form data when clicked on an INPUT field of TYPE IMG... which is pretty uncool for those using entire payment processes with such INPUT fields."
