Hey guys, When my Mac is turned on for more than 1 day this happens: Every icon goes down the screen and I can't even see the icons I had on the very bottom before. Clicking on them doesn't work. I have to click like 5 cm higher to open for example a folder. Does anyone know how I can fix this? It is very annoying. Here my specs: Mac OS X 10.7.5 1.86 GHz Intel Core 2 Duo 2 Go 1067 MHz DDR3 Thank you for your help guys!
