Hello Yeoman41,
This might be an easy fix - the way you describe it, you might be working in 'draft mode'. Check the title bar of the window, if "[Draft Mode]" appears there you need to switch back to the normal view. To toggle in or out of the draft mode, select "View" from the menu and click "Draft", or press "Ctrl-D". You can also use the toolbar button
to toggle the view...
Cheers...
