TOpenDialog file woes.....

I've been using TOpenDialog for selecting multiple files. Although the selected files are stored in the TString property "Files", I can't seem to access all the lines of this object. It will contain the first 17 files and a truncated copy of the 18th line. Is this a known bug? Is there are patch or a workaround?

  If OpenDialog.Files.Count>0 Then
      Begin
      For X := 0 To OpenDialog.Files.Count-1 Do
         Begin
         If FileExists(OpenDialog.Files[X]) Then
            Begin
            mtrLoadFiles(OpenDialog.Files[X]);
            Memo.Lines.Add(OpenDialog.Files[X]+' added.');
            End;
         End;

if OpenDialog1.Execute then
  Memo1.Lines.Assign(OpenDialog1.Files);

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thanks for the answer, but unfortunately it doesn't work. If you look at the source of Dialog.Pas, you'll see a buffer being used. I tried changing this buffer size and creating my own component, but it still didn't work.... perhaps I overlooked something. Thanks for any other input.
function TOpenDialog.DoExecute(Func: Pointer): Bool;
const
  MultiSelectBufferSize = 8192;
  ...
begin
   ...
    if ofAllowMultiSelect in FOptions then
      nMaxFile := MultiSelectBufferSize else
      nMaxFile := MAX_PATH;
   ...

I have 36 selected 36 files and it worked fine. What version of Delphi do you have?
