Well, there are no buttons at the bottom of this widget
window to even restore the plot to its original
condition. :-(
Here is something else that is weird. If I start
IDL 8 and just compile and run "TEST", then the
window appears, but it is *black*. Something only
appears in it if I put my cursor into the window.
After I put my cursor into the window, any subsequent
times I run it, the plot appears normally. We are going
to have to train people to "get IDL up to speed". :-(
Cheers,
David
