Thank you David, I can get the lat/lon values of the mouse position
doing:

result=CONVERT_COORD(event.X,event.Y,/DEVICE,/TO_DATA)

The problem I have is that my map coordinate system is not set up. So
when I call CONVERT_COORD I obtain the following message :
% CONVERT_COORD: Window is closed and unavailable.

I'm creating my images in a Z-buffer and when I restore the X device I
lose the map coordinate system. However, I have a copy of the !map
structure.

Is there a way to retrieve the lat/lon without using CONVERT_COORD ?

Thank you,
nata
