Improved Usability

• The mouse wheel now works in the Constraint Manager, allowing you to scroll up and down the tree view or spreadsheet view, or from left to right.

• The arrow keys allow you to browse the items in the tree view.

• The RMB option does not permanently change the selection set in the tree view.

• In version 9.0, if you tried to create a differential pair interactively and the selected items were not valid, the menu option was disabled. In version 10.0, the menu option is enabled but a warning is output to tell you why the selected items are not valid.
