for one unknown reason i can no longer drag a citation to another program be it openoffice, gmail, thunderbird... i have the impression that is linked to zotero 2.1.
the only quite arduous way to do it, is to click 'create bibliography from selected item' and then 'copy to clipboard' but dragging a citation was more easy
sorry, i did not understand your question: nothing happens
normally when you drag you have a little symbol with a "+" when you arrive on program where pasting is possible and that does not happen any longer
Mac OS X 10.6.6.
With Firefox 3.6. and Zotero 2.0. this was possible
