    static void MouseSelect(HANDLE hDlg, DWORD idStr, DWORD dwMousePosX)
    {
      SMALL_RECT dlgRect, itemRect;
      Info.SendDlgMessage(hDlg, DM_GETDLGRECT, 0, (LONG_PTR)&dlgRect);
      Info.SendDlgMessage(hDlg, DM_GETITEMPOSITION, idStr, (LONG_PTR)&itemRect);

      EditorSetPosition esp;
      Info.SendDlgMessage(hDlg, DM_GETEDITPOSITION, idStr, (LONG_PTR)&esp);

      int length=Info.SendDlgMessage(hDlg, DM_GETTEXTLENGTH, idStr, 0);
      int CurPos=dwMousePosX - ( dlgRect.Left + itemRect.Left );

      if ( dwMousePosX <= ( dlgRect.Left + itemRect.Left ) && esp.LeftPos > 0 )
        esp.LeftPos-=1;
      else if ( dwMousePosX >= ( dlgRect.Left + itemRect.Right ) && CurPos+esp.LeftPos < length )
        esp.LeftPos+=1;

      if (CurPos+esp.LeftPos < 0)
        CurPos=0;
      else if (CurPos+esp.LeftPos > length)
        CurPos=length;
      else
        CurPos+=esp.LeftPos;

      esp.CurPos=esp.CurTabPos=CurPos;

      if (bStartSelect)
