Folks,
The latest batch of function graphics bugs I am working
on is turning me into a depressed shell of a programmer.
Most of the bugs in my recent Bug a Day presentation
schedule seem benign enough to me. At least I can imagine
that someone could go into the code and fix them in a
relatively short amount of time.
The bugs I am working on today, however, seem to
be of a different sort. They seem to be ingrained
into the fabric of the function graphics design.
I might call them "bugs of unintended consequence."
It is exactly what one might expect of an overly
complex system that is extremely difficult for
a single person, not to mention a team of people,
to understand.
I'll be reporting on these in the days ahead, as
time permits, but it is getting harder and harder
to get up in the morning and see a bright future
for IDL along the current path. :-(
Cheers,
David

Along my tests with IDL command line, I had a lot of opened windows
too, even including an inactive IDL workbench ...

This worked. the window was iconified.

Well, not your version of IDL apparently. :o)

I had tbird running, along with several terminals (on different virual desktops), various incarnations of firefox, a
plethora of edit sessions, a couple two-three acroread processes, a dvi browser, and an online calendar app.

I agree. That is a loss.
I even wonder why this possibility has disappeared: maybe to get
compatibility with Eclipse's window management rules ?

Were other applications running while you did this?
I think it must be a problem with application "layering".
In fact, I suspect you wouldn't see the problem at all
if IDL was the only program running that put windows
on the display.
That said, I can't seem to get the IDL command line to
fail to bring the proper window forward on the display,
even with multiple applications running.
But, I do note that the beauty of the WShow command
in any version of IDL prior to IDL 7.0 was that it
would leave the focus in the command window. This
allowed you to bring a window forward on the display
and still type commands in the command window, allowing
you to see the effect of the command in the window as you
typed, even if your IDL application took up the whole
window space, as it usually does on a laptop.
That hasn't worked since IDL 7 and doesn't work in
IDL 8 either. Even in the command line version.
Cheers,
David
