Before I installed Tiger OS, PDF files would open up preview. This allowed me to easily save the document to the desktop. After installing Tiger OS, PDF files are opening up in safari browser making it more difficult to save. I need to hit "print largest frames" to save it as a pdf to desktop. This seems to sometimes cause compatability issues with pdf file when i open it on different computer and operating systems. I haven't been able to find a option to make all pdf files open in preview rather than web browser. Was wondering if anyone had any insight into this issue.
