Hy David!
I'm sorry, but I couldn't get the idea.
I've built 3 widget_bases with WIDGET_DRAW on them, and I load images
from the same area, but diferent points in time into them. My idea is
to link these images, so that when I move one image, the other 2 would
automatically move. The images are bigger than the window. That's why
I want to link them. We can do that in a very easy way with ENVI.
I keep my images in an info.
I want to draw in any of the 3 windows

thank you..
