I have recently installed AutoDesk Building Design Suite 2014 (Ultimate). I also have the 2012 suite and I did not uninstall it. When using AutoCAD MEP 2014, the application freezes when I click the calculator icon of the PROPERTIES dialog box to change the size of the arrow of a leader. Attached are the screenshots to show what I am referring to.
Your help is highly appreciated.
