Lately, my iMac monitor shows an annoying 'ripple' that is horizontal and evident when I scroll with my magic mouse. I have not run any diagnostic tests to see what reports might show, but I have run Disk Utility and AppleJack. No change. This 'ripple' moves down the screen slowly too. Any suggestions how to proceed? iMac - Leopard v10.5.8 Model Identifier: iMac7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Memory: 4 GB Bus Speed: 800 MHz
