Hello, I just got my imac today and am new to this and was wondering if someone could help me with a few things. First how do I get the browser to cover the entire screen similar to windows? Second how do I open multiple browsers at the same time? I think I messed up the screen resolution, what is the default? Last, the one button mouse is a little tough to get used to, is there some utility that explains how it works somewhere in OSX? I appreciate the help as this is getting a little overwhelming. Thanks
