The Properties are not updating when I click on Stacks unless I click somewhere else and then return to Cast to select the desired Stack again.

Steps to Recreate Issue:
1) Create two stacks in the Cast
2) Click one of the stacks or another object to view properties
3) Click one of the stacks again, but the properties do not change
4) Click on the stage or on the Zoom Out Tab
5) Return to the Cast/Properties tab and click one of the stacks and the properties will update

Thanks for logging this issue. It has been fixed.
