Every once in a while, my work computer goes crazy and decides to do things I don't want it to. Perhaps the most annoying thing is when it decides to scroll in Excel and Lotus Notes rather than moving the current highlighted item cursor.
Its really frustrating and time consuming trying to work with something that doesn't behave the way you want it to, or at least the way you're used to.
Luckily, the solution was incredibly simple. The "Scroll Lock" feature on the keyboard was on. Guess the cleaners accidently trigger the button while the computer is locked.
Kinda embarrassing, its sorta like complaining that everything I type is in caps without checking if the caps lock is on.
