An anonymous donor shared the secrets of recovering a cursor
location in data space from multiple map_set windows:

Your code looks something like this:

Window, 1
Map_Set, /Grid, /Continents, /Orthographic
Cursor, x, y & Print, x, y ; Select Colorado!

xs = !X.S
ys = !Y.S
mapstuff = !Map

Window, 2
Map_Set, /Grid, /Continents, /Cylindrical, Limit=[20, -160, 80, -40]
Cursor, x, y & Print, x, y ; Select Colorado!

WSet, 1
!X.S = xs
!Y.S = ys
!Map = mapstuff

Cursor, x, y ; Back in Window 1 data space!
