I have a 13" MBP 2.26 all stock. My computer originally came with Leopard, and I have since installed Snow Leopard. Now, when I press command + tab, to switch through programs, I am having stutters and delays. It is especially apparent if I press command + tab then Q to quit a program from that menu. It lags. I didn't have this "issue" when I was running Leopard. Can anyone tell me if they have noticed this, or a way to fix it? I have a feeling it has to do with my 2GB of ram. I have noticed that whenever apple releases a new version of software, if you don't upgrade the ram, you get slow downs. However, 2GB is a lot of ram. So if that's the issue, I won't be to happy.
