Unfortunately the "enterprise" seem set on it. Yesterday I was working with a new content management platform and I had to
downgrade my Internet Explorer to 9 because it only works with IE 7,8 and 9. Then that still didn't work because of some MSXML problem I couldn't fix and I ended up having to use a VM with XP installed and IE 8.
Un-be-lievable. I don't know who these Enterprisey IT managers are who are making these decisions but they seem to have a lot of power which they are using irresponsibly. And they seem to love IE.
