but did you really search well? 😉
first of all i guess you are talking about "Edit UVWs" window - UVW Editor
ok.. there is a way how find it and bring it back at the right place:
run this line:
windows.getchildhwnd 0 "Edit UVWs"
in my case the result is:
#(6425756P, 65552P, 0P, "#32770", "Edit UVWs", 4587736P, 6425756P, 6425756P)
the first element is the window's HWND
get it's position:
windows.getwindowpos 6425756P
in my case it's:
(Box2 4658 386 1548 1220)
change x and y position of the box to ZERO (left-top screen corner):
windows.setwindowpos 6425756P (Box2 0 0 1548 1220) on
