If I select a user or group when configuring a task in a workflow stage and then press Enter (as expected), the user or group is not added to the list. I have to click outside the box to add the item to the list. This is not intuitive and often leads to mistakes. I'm sure I have seen the same behavior in a language select box. It would be really helpful if any picklist type boxes have the same method(s) for selecting an item.
