I've never used the ZoomIn/ZoomOut features before. But
I just put it into a program that was zooming in a different
way. For me, when I zoom in, the draw widget gets twice its
current size!! Zoom out, it shrinks down again.

I don't know about you, but that is not what I expected
at all. (IDL 6.4 on Windows). I was sort of hoping the
view would zoom in and out. Why would you want the draw
widget changing size!?

Cheers,

David
