[Dx4win] DX4WIN 7.07.02 with MMTTY 1.66G Win 32 Error Code 87

[ARS NI5F]

Does anyone know how to fix this interfacing problem between DX4WIN 7.07.02
and MMTTY 1.66G? MMTTY works fine standalone. When integrated with DX4WIN
using the DX4WIN 'RTTY Window', and opening MMTTY first, the emulation works
fine with the virtual com ports.

The problem happens when I instead select DX4WIN | Windows | MMTTY when
MMTTY opens automatically. The MMTTY window opens along with many sequential
smaller error windows that say 'Win 32 Error. Code 87. The parameter is
incorrect'. Finally, a 'stack overflow' error occurs (not surprising!) and
Windows shuts down the process saying 'MMTTY control panel halted'. DX4WIN
still runs fine. The OS is Windows 7 Ultimate Build 7100.

This same configuration runs either method on a different computer running
Win XP SP3 and Elecraft K2 radio.
