Whenever i enter a formula, say "=sum(A2:E2)" by clicking on the particular cell to enter its coordinates (i.e. clicking cell E2 to insert 'E2' into the formula) it replaces it with ×10² with the 2 representing the row. It only happens on column E rows 2-9 but it is really annoying. Obviously the formula doesn't work. It happens in both excel versions i have (2008 and 2011), and on blank and other peoples excel documents (created on a different excel).
