Hi, Any other students up right now or others who might be able to help me? I'm trying to work on a research paper and everytime I click on a .PDF file on the web, which usually just open automatically, now, instead, all I get is that spinning logo on a gray screen. Why won't my PDF files open anymore? The spinning power meter thing just goes on forever. I recently installed Adobe CS3 and feel like that has something to do with it because it came with Adobe Acrobat Professional. (Or maybe it's something new with Leopard I didn't encounter with Tiger?) Any advice would be greatly appreciated!
