It seems to be some limit on minimal window size one can create from the Workbench: 484 x 335 on my machine, whatever smaller dimensions are asked.
From IDL Command line I can get a smaller (100 x 100) window but the window frame around the 100 x 100 drawing surface is enlarged in order that all icons at bottom can be displayed.
In addition, the couple of statements:
w = window(window_title="My window", dimensions=[500, 100])
ar = arrow([50, 200], fltarr(2) + 200., /device, head_size=3.)
creates, in case of the IDL Command line, a window of correct size but, of course, the arrow at Y-position 200, while window height is only 100 pixels, is likely clipped.

I would say almost certainly a bug in that version of IDL. That's the
version that the Onion reporter interviewed me about:

Hi Mike,
I tried a few Windows machines with the same version of IDL, and they all have the same problems. Not sure if my installation was wrong, or there is a bug, or something else caused it.
Thank you very much for your patient help. Gratefully appreciated.

I does not in the IDL 8.2.2 Workbench either. This looks like a bug in
the Workbench.

I can't reproduce that error in the Workbench or from the command line
(the widget system used for function graphics is different in these cases).

I also couldn't get that to happen.

But I did have problems (depending on Workbench/command line):
a) From the Workbench, I could not get the window to be only 100
pixels tall. But at least coordinates seemed correct.
b) From the command line, the coordinate system is screwed up. The
window shows up as 100 pixels tall, but to get the arrow and text to
appear in the window, I had to position them at over 100 pixels (200
pixels appeared to be the center of the window, making the device
coordinates of the window start at 150 and go up to 250).
Here is the code I was using:
pro mg_arrow_test
w = window(window_title="My window", dimensions=[500, 100])
t = text(50, 220, "$\it draw arrow here$", /device)
ar = arrow([50, 200], fltarr(2) + 200., /device, head_size=3.)
end

Many thanks Mike. Your explanation about different graphics is greatly helpful.
1) I added your line of code
ar = arrow([50, 200], [50, 50], /device, head_size=3.)
to my test script.
1a), the word "arrow" does not change color as other function names do.
1b), when running it, an error message appeared:
Unable to invoke method on NULL object reference: <OBJREF (<NullObject>)>.
1c), when commented out your line of code, and used the Annotate tools provided at the bottom of the graphic window, all other tools (such as Text, Oval) worked fine, but the Arrow tool caused an error message:
Unable to locate target descriptor: MANIPULATORS/ANNOTATION/ARROW
2), the window dimension still does not work on my machine:

The ARROW procedure is a direct graphics routine. The way to draw an
arrow in the Function Graphics system is to use the ARROW function:
ar = arrow([50, 200], [50, 50], /device, head_size=3.)

Many thanks Mike. Your explanation about different graphics is greatly helpful.
1) I added your line of code
ar = arrow([50, 200], [50, 50], /device, head_size=3.)
to my test script.
1a), the word "arrow" does not change color as other function names do.
1b), when running it, an error message appeared:
Unable to invoke method on NULL object reference: <OBJREF (<NullObject>)>.
1c), when commented out your line of code, and used the Annotate tools provided at the bottom of the graphic window, all other tools (such as Text, Oval) worked fine, but the Arrow tool caused an error message:
Unable to locate target descriptor: MANIPULATORS/ANNOTATION/ARROW
2) The window size is a problem on my machine:
{ x86_64 Win32 Windows Microsoft Windows 8.0.1 Oct 5 2010 64 64}
Is there
