ArgumentOutOfRangeException when adding text with AppendText

[Eldritch Palmer]

I can''t reliably reproduce this error, but this occurs sporadically when adding text to the edit control using AppendText.
The only way text is added to the control is with AppendText.

This is all code that''s related to the editcontrol in the form:
editControl1.ShowOutliningCollapsers = false;
editControl1.Text = string.Empty;
editControl1.SaveOnClose = false;
editControl1.UseXPStyle = true;
editControl1.WordWrap = false;
editControl1.ShowLineNumbers = false;
editControl1.Languages.Clear ();
editControl1.Language.Lexems.Clear ();
editControl1.Language.Splits.Clear ();
editControl1.Language.ResetCaches ();
editControl1.ConvertOnLoad = false;
editControl1.ReadOnly = false;

Here''s the stack trace of the exception

Hi Palmer, I have tested for this issue using v4.2.0.37 and was not able to see the problem.Please refer to the test sample attached here and let me know if I am missing something.If I have not understood your specifications correctly, could you please modify the sample to show the problem ?

Hi Ebenezer, Sorry for the late reply. Your test sample doesn''t look particularly different from mine. Unfortunately I can''t reliably reproduce the problem, it just pops up sporadically. I''ll get back to you if I ever manage to get a reliable repro sample. >Hi Palmer, > >I have tested for this issue using v4.2.0.37 and was not able to see the problem.Please refer to the test sample attached here and let me know if I am missing something.If I have not understood your specifications correctly, could you please modify the sample to show the problem ? > >Regards, >Ebenezer.P >
