Started experiencing this today, while building an app when changing any details on the properties screen on the right hand side of the editor it won't change the values and just revert to what was there before. It's doing this independently of the property I'm trying to change, whether it is X and Y values or Height or Width of the Text itself, or even the visibility toggle button, it just won't take it. I always need to use the top of the page formula Bar.

Not sure if anyone else is experiencing this?
