Opening property inspector disables UIcontrols

I have a custom UI, when I want to debug or instect an item anywhere in the UI with the Property Inspector, UI controls such as edit boxes, pushbuttons, tables etc all become a selectable item for the Property Inspector, rather than responding as they normally would. Once the property inspector is closed this behavious still continues, so the UI is no longer operational.

So every time I open the Property Inspector I have to close and reopen my UI then reload data that I an analyizing. This is not very efficient.

I'm using the old figure not the new uifigure.

This may be a bug, but it would be nice if there was a way to properly close teh Property Inspector, especially now that it opens every time you double click in an object in the workspace.
