No. There is no way to get the kind of information you need from
a regular IDL window. There are several possible solutions with
draw widget windows. In fact, you could probably figure out a
way to use draw widgets in your regular IDL program and
achieve what you want. I would experiment with widget
tracking events and using WIDGET_EVENT from your non-
widget IDL program to find out what window the cursor is
located in. You could do this, for example, from a normal
IDL loop.

Yours,
