Right. In hospitals there was a very popular medical imaging web information system, GE, Maybe? It rendered with an ActiveX control embedded in IE6. It didn't work in IE7.

So a lot of customers I worked with couldn't move past IE6. "No way, everybody need to be able to see those XRays images."

We even tried, without success, to organize the quick development of some sort of replacement for that, umm, "legacy" ActiveX control.
