I really don’t know if it is a problem with my Scrivener preferences or with my system preferences (OS X lion) but whenever I leave the QuickReference window and go back to the main editor then the QR window disappears behind, what in fact makes this feature useless. Is it really a problem or is it just my ignorance of basic things?
Go to the Window menu and select “Float QuickReference Panels”. This will ensure they always remain on top.
All the best,
