Description of problems: Moving down from bottom right corner of Betty takes me to center of Mon 1 on Homer Moving up from Mon 1 of Homer attempting to go to Betty does not work. Moving up from top left corner of Mon 2 from Homer takes me to Center of MacPro Moving left and right between Betty & MacPro works fine
