Thank you. The problem you reported has been corrected and will be included in the next product release.

Fixed versrion of Sort method is:

void CXTPItemConstraints::Sort()
{
 CStringList lstSorted;
 POSITION pos = GetHeadPosition();
 while (pos)
 {
  CString str = GetNext(pos);
  
  POSITION posSorted = lstSorted.GetHeadPosition();
  POSITION posInsert = (POSITION)-1;
  while (posSorted)
  {
   if (GetNext(posSorted) > str)
    break;
   
   posInsert = posSorted;
  }
  
  if (posInsert == (POSITION)-1)
   lstSorted.AddHead(str);
  else if (posSorted != posInsert)
   lstSorted.InsertBefore(posInsert, str);
  else lstSorted.AddTail(str);
 }

 RemoveAll();
 AddTail(&lstSorted);
 
}
