Hi all I am a Win XP PC user who is new to to my iMac and I am finding it very difficult to get things working. For example my Grab' program doesn't work, when I click the icon nothing happens. I installed Skype but although it works there are no menues or anything to set up the options I want. How do you uninstall programs on a Mac? Perhaps the Skype needs to be installed again??? I installed my favorite browser, Firefox, but it doesn't work well, for example I can't find many of the settings that my old Windows Fairefox has, how do I tell it to always keep the tabs when I shut it down? The iMac is a beautiful looking machine but the learning curve is steep and is not aided by what I consider is a very poor and difficult to use help system.
