Warning message in MultiTerm when closing the "Catalog Categories" window required

We've seen it quite a few times that users complain about the left panel in the Termbase Management view being empty when they want to change their termbase definition or the termbase layout, etc. In most cases, they had, by accident, closed the "Catalog Categories" window by clicking the small "x". Wouldn't it be good to have a warning message that appears when this "x" is clicked to notify the users of this situation?
