Sorry this is super NON technical, but I've just come back to Zotero after a while away, and I can't seem to work it properly. I've lost a bunch of PDFs that I thought I had saved, and I can't pull up the Zotero page using the little verically sliding tab that used to be in the bottom right hand corner of my screen. I've updated Zotero and Plug ins...any help greatly appreciated...I'm using Firefox and Word...Amber
