I'm trying to get some text from a PDF I've been given by someone and Preview is (I've no idea why) having a severe problem copying text. I select the text I want from Preview and paste it into TextEdit. I go back to Preview, select more text, copy, and when I come to paste it in - the previous text is pasted in! I've closed and re-opened Preview, the PDF and TextEdit and the problem is the same. I'm ready to will my iMac and Preview to death - what am I doing wrong? Does Preview just suck at PDF support?
