You may have found by now that to get "normal" menus, you need to
use the MBAR keyword on the base widget. This is not an option in
WIDED, so it is necessary to edit WIDED-generated procedures.

Yes. A warning: There are a number of widget bugs in the Windows
version of IDL. Some are in RSI's software and some are caused by
graphics card drivers. In particular, if you use a menu bar under
Windows, you may find that 1) Two resize events are generated when the
widget is realized, and 2) Text or draw widgets placed below the menu bar
will not be positioned correctly (this can be compensated for with
negative padding and a "spacer" base widget).
Also, when I recently switched from Windows for Workgroups to Windows 95,
three new bugs appeared (and one went away).

When I look at my news reader which I currently use to write this
reply it has the same grey button that look exactly like those
the WIDED presents. I do this running both IDL and the news
reader from MS Windows 3.1.

The WIDED is limited in its capabilities, however, the IDL windows
toolkit has its limitations: As all widgets should run on every
windowings system (OSF Motif, MS Windows (different flavours!),
Mac) there are either several restrictions you have to live with
or you must pay a lot of money for a GUI buider.

The demo program is written in IDL and the source code comes
with IDL. Actually, it is interpreted each time you activate it. Thus,
if you like parts of I you can copy that part to your local disk and
modify it. I did so several times to gain performance. All programs
are well documented and provide a good entry for beginners.
In order to make the programs better readable some tricky code
to speed up performance was avoided...
BTW the demo programs are stored in c:\rsi\idl40\examples\general

Sure, what's your problem ?
There is a German www page for IDL on our webserver:
http://wwwpc.hrz.th-darmstadt.de/prog/grafik/idl-4_0.htm
with a couple of links to other web and ftp servers.
Hope this helps
