After reading about the problem with 3d icons in templates, mainly when a 3d
icon is clicked to quit the application, I had a look at writing some code in C
to fix the problem:

/* The alarm handler to do the exit */
static void delayed_shutdown(int at, void *handle)
{
    wimp_mousestr mouse;

    /* Get the state of the mouse */
    wimpt_complain(wimp_get_point_info(&mouse));

    /* Check SELECT, MENU and ADJUST buttons */
    if (mouse.bbits & (wimp_BLEFT | wimp_BMID | wimp_BRIGHT))

	/* A button is still pressed, reschedule this handler */
	alarm_set(alarm_timenow() + 10, delayed_shutdown, NULL);
    else

	/* All buttons released, safely exit */
	exit(EXIT_SUCCESS);
}

/* Call this routine when you want to exit */
static void delayed_exit(void)
{
    /* Install handler */
    alarm_set(alarm_timenow() + 10, delayed_shutdown, NULL);
}

This appears to solve the problem (i.e you don't get the address exception at
address 0x03nnnnnn somewhere in the WindowManager module), though there may be
more elegant ways of doing it.
