double click reaction sds

There is a command in AutoCAD  -  DBLCLKEDIT. If DBLCLKEDIT is off, AutoCAD's double click reactoin is inactive.

 

In Bricscad 9  sds I do:

 

case SDS_CBLBUTTONDBLCLK:

//sds_printf(_T("\nsdsMigrate: SDS_CBLBUTTONDBLCLK"));

MessageBox(sds_getmainhwnd(),L"SDS_CBLBUTTONDBLCLK",L"INFO", MB_OK);

break;

When I doubleclick on text entity, after my MessageBox appears Bricscad's text editor. Is it possible to make the appearance of Bricscad's text editor  impossible.
