Not saving when open in two tabs

[dasymington]

If you have an item open in one tab and then you open the same item in another tab and update the item details there, UR doesn't show the changed data in the item in the first tab.

I haven't noticed this before, but today it lost me some vital data. I've closed UR and opened it again and the error is repeatable. Earlier I got a message I hadn't seen before about it not being possible to update the database because it was in use by someone else.

Is this the way it's supposed to work?
