PowerWindows stuck

Running Resolve 17.1.1
In some behaviours the PowerWindows get stuck - as in: can't move them around.
Can be confusing to explain so here we go:
Let's say I want to tweak around a bit with the curves in clip A. After a while I move over to clip B. There lays a PowerWindow on a currently selected node. The Onscreen Control Menu is set to display the window. When I then want to move around the PowerWindow it is stuck. I then have to move over to a different tool - i.e. back to curves - and then back to the PowerWindow tools. In other cases I switch to the tracker tool - other tool so 'unlocks' stuck window - while still be able to move around window since Onscreen Controls remains set on PowerWindows (saving one click).
