I have the Mac G5 version 10.4.11. Lately, I have been having problems with the computer freezing whenever I click onto anything, such as a drop-down menu, a folder or an application. In all these cases, I experience the Spinning Beachball of Death where the computer hangs and nothing happens. Although repairing disk permissions on the Mac HD solves the problem immediately, its positive effects only last for 1-2 days and then the freezing problem returns. I am not downloading online files during these intervals and I am not sure why the freezing problem returns. Thanks for any tips or suggestions.
