Press "P", that's it.
I am also having this problem. I've found work arounds that only sometimes work.
Restarting the game - doesn't work often enough maybe 1/10 times or less
Opening the Game Settings and changing something (basically anything) sometimes works.
Basically what I've noticed is that when this happens my number pad (which I use most of the time) stops registering them as numbers and instead treats the number pad like number lock is off. It also makes scrolling with up, down, left, and right a lot faster. My normal number keys don't work at all.
Maybe to some this would seem a minor inconvenience but for me it's pretty big, I can deal with it it just gets really annoying. I've been playing The Sims since the first one was released and I have a certain play style which is hard to break after years upon years of playing.
I have a Razer BlackWidow keyboard if that is any help to anyone.
did you try hitting the p or ESC key ?
