Having problems with Outlook 2007 email, can't see advanced menu with reco'd 3840x2160 res. Had to change to 1280x1024 to see the 'more settings' option on the screen then managed to change settings. But, I then changed res. to even lower res. but now I can't see the screen res. option to go back to previous res. So how do I restore default screen res. please ? /Dude of the sand
