Funny seeing my screenshot being used here.
That guide mentioned in between won't help you at all, if you don't know how to hook the minimized map from the regular map and re-set the layout of both instances.
It will bug out your map window frame over and over again, until you either teleport or relog, even if you redo the map window for the big/general map size.
People around here won't release stuff properly, because they are sloppy and not quite skilled in anything.
You need few other offsets along from those being ripped and also need to adjust quite a few UI elements to suit the window properly for the overall clean look.
No, I won't release the offsets. People should start to use their brains.
