And it does it in every game, even when you start a new one?
I did a bit of research, and it looks like this was a common bug. However, most of what I saw was one to two years old. Is your game fully patched and up to date?
Possible causes I saw mentioned were very full sim inventories, bookcases with a lot of books, and houses with a lot of items. The theory was that all of these items pushed the game beyond the computer's capabilities to run it, which caused the hand tool to freeze up. For some players, deleting items in the house would fix it. For others, it didn't because they say that there weren't a lot of items in the house to begin with.
Another issue I saw mentioned a lot was a mod related bug. If you're using mods, I'd suggest seeing if there's an updated version or removing it altogether to see if that fixes the problem.
Other than that, I can't be of much more help I'm afraid. But there might be someone else who knows a bit more about it than I do.
