Am I the only one who is having this problem? Prior to 10.10.2, when I did calculator operations in Spotlight (for example, 2+2 would then show =4 in the main bar), it worked. After updating to 10.10.2, it no longer does any calculations. I've turned off and back on the Calculator checkmark in the main Spotlight preferences, but no dice. Can anyone else report back if they're having the same problem?
