I noticed a difference in behavior between Mac and Windows with details. In the Mac version, the detail is like a crop window. So moving the points of the detail border, will just alter the crop. This is what I like, the scale of the detail stays the same. Not so in the windows version: if I move the points, the content gets scaled.
My vote is therefore to adopt the way it is done on the mac.
edit: btw if I scale the detail with gumbal in y-direction, the detail gets scaled, if I scale in x direction, I get different behavior: it acts as a change to the cropping only…
edit2: it behaves like Mac when the detail is locked
edit3: when the detail is a perspective view, it works differently, and is buggy as well: If I lock a perspective view, then deselect and reselect, the lock checkmark gets removed, yet when I double click in the detail to change the view, it is still locked. The only way to unlock it again, is to check the lock checkbox and uncheck it right after
