I received update notice for adobe reader version 9.4.6. With Adobe's help I finally was able to download flash player 10.1.102.64 for my Mac Powerbook G4 version 10.5.8, Power PC processor (1GB mem). Is the 9.6.4 version compatible with my computer or will I have the same downloading problems I had trying to update to the latest version of Flash Player? Currently PDF documents won't open from email attachments or many websites, such as for online movie ticket purchases. I have to save them to my computer first, then open. Hoping a newer version of Reader will fix that problem. Which version should I have and how do I download?
