I have a Numbers file that keeps track of insurance payouts. It's absolutely bare bones: one font, no graphics.
Suddenly, I find that when I open the file, my MacBook Pro starts becoming extremely warm and sets off the internal fan. Nothing else is running. It gets especially hot if I magnify the sheet using Cmd - >.
Anybody have a clue about what's going on?
