I just bought myself a macbook with leopard installed and there are a few things about the operating system that I don't really understand. The first thing I'm wondering is why I can't cut files. I can copy and paste files fine but I can't command + x them and in the edit menu the option cut seems to be permanently greyed out. I'm finding this quite annoying. Another thing I'm wondering is how can I get a window to fill the entire screen? In some programs, like mail for example I can just hit that little + button and the window nicely fills up the screen. Other programs though like itunes and firefox don't act as nicely. hitting the + button in these programs just makes it jump between two different sized windows. I also bought myself one of those apple wireless mighty mice and I'm wondering if it's possible to set it so that if I click button 3 on the mouse (the little scroll ball) I can get a file to open in quick look. currently this button is set to dashboard or something like that. Thanks a lot for any help.
