I call appl_init when I start up.

/*
	Here is the code that works fine when executed from the Laser C shell
	but won't respond to the mouse buttons when run from the desktop
*/

int p_wait()
{
	int ev_mmflags = 0x3;	/*	keyboard evnt & mouse evnt */
	int ev_mbclicks = 1 | 256, ev_mbmask = 3, ev_mbstate = 0 ; 
	int ev_mm1flags = 0 ; 
	int ev_mm1x, ev_mm1y, ev_mm1height, ev_mm1width ;
	int ev_mm2flags = 0, ev_mm2x, ev_mm2y, ev_mm2height, ev_mm2width ;
	int ev_mtlocount, ev_mthicount, ev_mmox, ev_mmoy ;
	int ev_mmobutton, ev_mmokstate, ev_mkreturn, ev_mbreturn ;
	int ev_mmgpbuff[8] ;
	int status ;

#ifdef DEBUG_P_WAIT
printf("calling evnt_multi, Numahead = %d\n", Numahead) ;
#endif

/*
	No it's not returning here when run from the desktop.  I have
	to strike a key to get it to return
*/
	if( Numahead > 0 )
		return P_KEY ;

	status = evnt_multi( ev_mmflags, ev_mbclicks, ev_mbmask, 
			ev_mbstate, ev_mm1flags, ev_mm1x, ev_mm1y, 
			ev_mm1width, ev_mm1height, ev_mm2flags, 
			ev_mm2x, ev_mm2y, ev_mm2width, ev_mm2height,
			ev_mmgpbuff, ev_mtlocount, ev_mthicount, 
			&ev_mmox, &ev_mmoy, &ev_mmobutton, &ev_mmokstate, 
			&ev_mkreturn, &ev_mbreturn ) ;

#ifdef DEBUG_P_WAIT
printf("evnt_multi status: 0x%x\n", status ) ;
#endif
	
	if( status & 0x2 )
		return P_MOUSE ; 
	else if( status & 0x1 )
		{
/*

	stuff keyboard entry into console input buffer
*/
#ifdef DEBUG_P_WAIT
printf("ev_mkreturn = %c (0x%2.2x)\n", ev_mkreturn, ev_mkreturn) ;
#endif
		Nextinchars[Numahead++] = ev_mkreturn ;
		return P_KEY ;
		}
/*
	shouldn't get here
*/
	return P_KEY ;
}

When I run from the desktop with my debug statements turned on, I don't
get a return and status from evnt_multi until I use the keyboard. The
setting of the high bit in mb_clicks is not the cause. Giving it a
mask for the left mouse button without the logical negation, the simplest
case, it still has the same problem. I have hardly run the program 
outside of Laser c, but I think it was working from the desktop previously.

Any ideas?
