QuestionPoint and IE7

I've had a few questions from librarians wanting to upgrade their Internet Explorer browser to version 7, which Microsoft just released. The official word from QuestionPoint is: don't upgrade yet. They're having some difficulties making cobrowse play nicely in IE7.
(Related note: apparently OCLC (which owns QuestionPoint) has banned all their employees from using IE7. A number of their products and services do not work well in IE7.)
