The page setup has changed to 'portrait' and Page Setup will not change it back to landscape.
When I switched on this morning Adobe Reader installed an update and recommended removing Realplayer. I looked up how to do this but it doesn't seem to be on my machine. When I started Firefox the page setup had changed to portrait. Going into 'PAGE SETUP' and changing the setting to landscape had no effect.
