[Zope] exuser older not working in 2.9.0

[John Huttley]

HI,
In a burst of enthusiasm, I trashed my zope 2.8 for windows and 
installed 2.9, with a new instance.
I've reloaded ZStyleSheet and ZODBC, which have come up in the ZMI ok 
and exuserfolder, which doesn't.

In 2.8, there were some minor issues with fcrypt which meant it came up 
with a broken box icon, initially.

I've installed it in 2.9, fixed the issues and nothing comes up in the ZMI
Running Zope in the console doesn't show any relevant messages.

I'm at a loss as to how to debug this.

Any help gratefully received.
