The screen size changed unexpectedly yesterday on my live.ca account.   It's gone to a larger size so that I have to scroll through to see the rest of the page.  My finger must have dragged across something, but I have no idea what.  Can't find how to put it back to normal and turn off whatever pesky feature the damned programmers have put there.
I really wish someone could explain to those guys that only a small proportion of their users are computer aficionados.  K.I.S.S.

Everything is normal on my other computer, and everything is normal on everything except the Outlook account (I use live.ca)
The laptop with the issue uses Window 8.
