[Zope] Cut, copy & paste

I am returning to some Zope work after a long absence and I cannot get cut, copy & paste to work in the management screens. I have a brand new install of 2.2.2 on NT4/SP6, using IE5 (with cookies enabled) and if I cut/copy something in the management screens, the paste button appears as expected. If I go to another folder, no paste button. If I go back to the original folder the paste button has disappeared. This happens as the super-user or any other user I have defined. A quick search of the mailing list and Zope site failed to turn up anything. Can anyone shed some light on this, as it's a giant pain to have to export each time I want to move something. TIA Robert PS Please cc me directly on this as I am in digest mode. Thanks.
