My wrapper was sending DG_CONTROL/DAT_NULL/MSG_CLOSEDSREQ to talk to the dsm.
I think I sent CloseDSRequest since otherwise there was no DG_CONTROL/DAT_PARENT/MSG_OPENDSM response.
This seems to be the cause of the problem.


DSM_Entry(&WrapperID, &AppID, DG_CONTROL, DAT_NULL, MSG_CLOSEDSREQ, (TW_MEMREF)NULL);

DSM_Entry(&WrapperID, NULL, DG_CONTROL, DAT_PARENT, MSG_OPENDSM, (TW_MEMREF)&in_hWnd);
DSM_Entry(&WrapperID, NULL, DG_CONTROL, DAT_IDENTITY, MSG_GETFIRST, (TW_MEMREF)&SecondDSID);
DSM_Entry(&WrapperID, NULL, DG_CONTROL, DAT_IDENTITY, MSG_OPENDS, (TW_MEMREF)&SecondDSID);
DSM_Entry(&WrapperID, &SecondDSID, DG_CONTROL, DAT_USERINTERFACE, MSG_ENABLEDS, (TW_MEMREF)&twUI);
:

Is there a way for the wrapper to open the dsm while maintaining its conversation with the app?
