Rootless windows are automatically refreshed if you provide
a Xwindows "backing store":
Solution 1: let IDL provide the backing store by typing:
device,retain=2
See the IDL manual for details.
I have put the above line in my $IDL_STARTUP file (see manual).
Solution 2: let MacX 1.2 provide the backing store. Select this in the
MacX Display Preferences (Edit menu).
Good luck,
Fred.

Still struggling with IDL via MacX. I am upgrading IDL to a newer
version - maybe that'll help with some of the problems.
Thanks for the tips: I did find the patch for twm crashing. I'll also
try increasing the memory size from 5000 to 10000K. I'm still pondering
the suggestion to use VersaTerm-PRO; while I do have it, I've rarely
used it (I use NCSA Telnet). Good tip on the colormap entry warning,
I'll check private color maps. But is that related to the X windows
protocol error?
I was initially running rootless, but I reluctantly went to rooted because
the MacX window manager chooses its default window locations poorly; for
example, its default for the first IDL window is *under* the menu bar
across the top of the Mac screen.
Even more indivious, plot windows appeared far off to one side with only
an edge visible, and the data in them was lost (i.e., was not refreshed
when I dragged the window fully onto the screen unless I physically
replotted). With twm, I can position windows with a click when they are
being opened, so at least they are fully on the screen with the data visible.

I run IDL through MacX all the time. I'm using MacX 1.1. There is a newer
version that others around here use successfully.

You may have other X clients that have already grabbed entries (perhaps all
of them) in the shared color map. If you need lots of colors, you may need
to turn on a private color map. Private color maps let you use all 256
colors at the expense of flashing the LUT when you move the cursor around.
See the IDL manual on the X device.

In the Get Info dialog box for MacX, just set the memory as high as you can
afford before you start MacX. I always start MacX last of all my apps in
case I need to restart it to change the memory size. For long animations I
use 10 or 12 MB. You can figure out how much you need based on the size
and number of your pixmaps. The About MacX window will show you how much
memory you have and how much is in use. You can watch it fill up as you
load an animation.

I think this may be window manager problem, almost certainly memory
related. Are you trying to run in a root window under MacX? If you let
the Mac handle the window management you may have better luck and you won't
need a window manager (twm). I set my DISPLAY to bowman.tamu.edu:0.2 for
color, rootless client winds. Each client appears in its own Mac window.
This may be different in MacX 1.2. Check the MacX manual.
