I'm having the same problem, mostly when I click on sims themselves. But it doesn't happen all the time, even on the same lot, so it's hard to pin down.
This ^. I do find that if I click repeatedly, the next menu will open up and then the more option works properly. It does aggravate the old carpal tunnel, though. I've been wondering about it for a while, but not enough to do the binary dance. I delete the cache files when it starts happening often. I think that helps, but it's so random, it's really hard to tell if does or not.
