Break symmetry command temporarily prevents Actions button from working

Using the "Break symmetry" command (Alt+Shift+Click or whatever on a part) prevents you from being able to click the Actions button immediately afterward (i.e. to go mode where you can assign Stage, Gear, Light, Custom01, etc).  I had to add/remove a part to get it to work again.

linuxgurugamer confirmed as a bug; low priority for the moment.
