What I mean to say is that the functionality hasn't changed, It works the same way in v6 (322.7) as it currently does in v7 (324.3).
Pressing escape does not deselect the object in any instance on any property anywhere in either program, however if I've clicked on the object itself, without
touching the properties pane, then escape will clear the selection.
I had assumed you wanted this to change based on how you phrased
This does not appear to be fixed in build 324.3 of the Editor
I've followed all the steps you provide and still find that while I may deselect the property, Ill never deselect the object itself.
