it doesnt happen with every application and is quite random... and i dont think its always when i quit but most of the times it is....
well its a desktop and i believe its command + control + esc to force quit an application but when it does freeze, it just wont respond when i try to do that and i sometimes have to resort to holding thw power button... and on the rare occasion, it doesnt listen when i use the power button
So the whole computer is freezing? Not just specific applications?
