:-), i've reported this problem to IBM sometime in 1993. the last version
of OS/2 you can kill a thread with a pending MouRead was OS/2 1.3. 

I changed all my Mou* calls into the equivalient DosDevIOCtls.

:-), looks like same code. (note: the following is from my 16 bit app)


...
#define _MouseReadEventQue(pme,pwf,hd)\
      DosDevIOCtl(pme,pwf,MOU_READEVENTQUE,IOCTL_POINTINGDEVICE ,hd)
....

static void _ReadMouAsync(void)
{
 MOUEVENTINFO mouseev;
 USHORT usfWait = MOU_WAIT;
 _MOUSEENVIR *pme = _pme;

 while (1)
   {
    if (_MouseReadEventQue(&mouseev,&usfWait,pme->_hmou))
      DosBeep(100,100);
    DosEnterCritSec();
    pme->_mouseev = mouseev;
    DosExitCritSec();
    DosSemClear(&pme->_ulSemMoDataAvail);
   }
}

you can terminate such threads. PS: under OS/2 2.1 the system traps a few
seconds after program shutdown, when you try a DosClose of the Mouse Device
driver. (this was NO problem under OS/2 1.x and 2.0). I've never tested it
with later versions. it is ok to terminate the main thread of the app and
this mouse reading thread will terminate too.

 WARPED!, Mario
