Since installing 10.2.5, I have observed that Acrobat (5..0.5) quits everytime that it launches (which it does automatically, everytime that I download a PDF file). If I launch it manually, it also quits. Has anyone else noticed an apparent incompatibility of Acrobat 505 with 10.2.5 ? Acrobat Reader 5.1 is fine. regards, Trevor
