The 'default title' control on the master's screen of the mansion is not covered when 'unlock abilities' and 'inspect looks' show their windows. It is covered by the 'see relatives' popup.

I tried to some quick fixes to show the windows as modal but it wasn't happening for me. I'll leave it for someone with better GD/windows knowledge to sort out.

It's just a matter of node order on the tree. Moving it higher in the list of children changes the render order and fixes this problem. 

Edit: Higher in this context is closer to zero.
