Attachments appear as items also
It seems that many attachments --- links to web pages and screen shots most often --- appear both as attachments to that item and as independent items. In some cases, I can remove the item level attachment but in others that removes the related attachment as well. I have gone through and deleted these duplicate attachments and re-linked, but they re-appear in another session. It happens with journal articles and newspaper articles as well. Small issue in an otherwise great tool!
I'm on a MacBook Intel Core Duo.
