MessageDlg buttons not in right order

Hi Experts, I have a 3-button MessageDlg like this:

MsgVar := MessageDlg('Problem found!'+#13#10+#13#10+
                        'Click YES to proceed and display each occurence of this.'+#13#10+
                        'Click IGNORE to proceed without showing any more occurrences.'+#13#10+
                        'Click ABORT to abort this process altogether.', mtWarning, [mbYes,mbIgnore,mbAbort], 0);

if MsgVar = mrYes then FoundDiscrepancy[i] := FALSE
else if MsgVar = mrIgnore then FoundDiscrepancy[i] := TRUE
else EXIT;

Select allOpen in new window

When it displays, it shows the 3 buttons in the wrong order. It shows them as
YES   ABORT   IGNORE

when it should be:

YES   IGNORE  ABORT

However, when I do click a button, it does seem to perform the appropriate action - it's just the order that's wrong. Any idea what would be going on?

Thanks!
