Probably a "me" issue since I don't see anyone reporting it, but wasn't there a right-click menu for things you could click on in the world?
For instance:
1) I can light or extinguish a candle, but cannot pick it up. If I right-click the candle...nothing happens.
2) To unlock something I can't right-click and choose unlock, I have to open my inventory, right-click on thieves tools (right-click does work on inventory items), then click on the locked object.
