Openwindows 3.0 anomaly with widgets [message #454]

Under IDL v 2.3.2 and Openwindows 3.0 on my Sparc 4/75 running SunOS 4.1.1,
I get the following error message *sometimes*

IDL> ?
% Compiled module: MAN_PROC.
% Compiled module: MP_WIDGETS.
% Compiled module: XREGISTERED.
OPEN LOOK Toolkit Error in application "imslidl": Can't allocate gray pixel

The error occurs when there are no more colors available in the shared color
map. I avoid the problem by either placing this line in ~/.Xdefaults:

Idl.colors: -16

to keep 16 colors in the color table free or by creating my first window with:

window,colors=-16

The two methods are equivalent.

Does anybody else see this error or know of other ways to avoid it?
