When rightclicking on some stuff it can go under the other borders, see below as example.

Yeah I know about this. Unfortunatelly i can't do much about this. I have an idea which I'll try tommorow but I don't promise anything.

BTW the solution I found for nameplates might apply here. Basically movers parent window must have "FixedHudStratumLow" or normal/high not sure, and then have wndMovers:ToFront() after wndMovers:Show.

Problem with movers is that some have to be over others (players resource bar is on top of unit frame and is higher on z-axis). Atm every mover is in the same stratum as its parent UI element to make sure its all OK and I guess it could be done that every mover is in the same stratum somhow. I was more thinking about separating right-click "precision" menu from mover and when right-clicking mover that menu would get binded to that mover and becase its not directly movers child it can be in different stratum.
