  Remarks             DESQdisperror() will popup an error window under
                      DESQview, displaying the string msg. The message
                      must be less than 4K (<4096 bytes) in size. The
                      window will be of size width by height. If either
                      or both values are zero, the default values will be
                      used. The segment is segment of the object handle,
                      and the flags is a bit field with the following
                      important values:

                           bits 13,14:  which mouse button will remove
                                        the window
                                     00 or 11 = either
                                     01 = left
                                     10 = right
                           bit 15:  beep when displayed

                      For your convenience, DVERROR_LEFT, DVERROR_RIGHT,
                      DVERROR_EITHER and DVERROR_BEEP have been #defined
                      in multihk.h.

  Return value        returns 1 if the left mouse button was pressed, 2
                      if the right mouse button was pressed and 27 if ESC
                      was pressed.
