Hi. I currently have a problem with preview. A few weeks ago, as I was saving multiple webpages in PDF, Chrome asked me if I wanted to open them all in one document, to which I confirmed. The next day, as I was opening other PDF documents in preview, I realized that all my documents were opening up in one window still. This made consulting different documents a big hassle. I tried to look for solutions, but nothing has come up. In order to open documents in separate windows, I have to manually right- and select 'Open in New Window' each and every time. Are there any permanent solutions to this problem? Thanks.
