I am running Interactive unix 2.0.2, with TCP/IP 1.1.2 and X-windows 1.2.

A program that compiled under X11R4, and ran fine compiles under ISC's
X11R3, but will not run correctly. Specifically, I have a work process,
which is registered with the call XtAppAddWorkProc( app_context, proc, NULL).

Under a system built with the MIT X11R4 tape, on a sparcstation, this works
fine, with the work process being called regularly when there are no X-events
pending. However, under ISC's X, the work process gets called once only.

Specifically, this is the code:

.
.
.
main(argc, argv) int argc; char **argv;

{
XEvent		event;

	/* initialize the socket interface */
	conn_obj = initialize_socket();
	NPGetSocket( conn_obj, &sock); /* This is proprietary stuff... */

	/* perform windows startup stuff */
	initialize_windows(argc, argv); /* Open display, etc... */

	/* Add the server background process */
	XtAppAddWorkProc( ac, server_work_proc, NULL);

	/* do the X loop */
	for(;;) {
		XtAppNextEvent(ac, &event);
		XtDispatchEvent(&event);
		}

}

XtWorkProc server_work_proc() {
/* This process is run as a work process in the background of the X loop. */

printf("In process\n");
}
.
.
.

What is wrong??
