The problem is that the XtOpenDisplay call did not specify the display.

Looks like a fix is to insert p instead of NULL. (Tested rudimentarily.) Prof. Ripley replaced that NULL with dsp -- p is normally the same. It's in svn (r43300 on he trunk, r43301 on R-2-6-branch). It built without a hitch, and the fix solves my problem. P. Dalgaard also pinpointed the problem. And confirmed Xt was involved :-) Apparently an XOpenDisplay on the specified display may be followed by an XtOpenDisplay, previously on the default display. Thanks to everyone who helped figure this out and fix the problem! /Christian Brechbuehler [[alternative HTML version deleted]] __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
