Ah, thanks for the reply, but that’s not what I’m talking about. I have the “Pages” thumbnails turned off already; what I’m talking about are the page previews that are created when you save a document. I have that option deselected both in preferences and in the ‘save as’ dialog, but it still often gives me a status bar while it’s saving that says “generating page previews” and can sometimes get hung up there for quite a while.
