Sort from ribbon icon not working

If I click on the data field in data view or form view I want sorted, and click on the sort icon at the top ribbon the dialog comes up and hangs there. I hit escape key and it gets it out. If I use the sort from the main menu it works?

It looks like this is a new problem (or at least not reported before). The problem is not clicking the icon, it is that the first time you open the dialog the layout is incorrect. Then when you open it again it works ok, whether, you use the icon or the menu. I’ve added this to the bug list.
