That's why I love SciTE. I just tried it with 126 MB text file and it didn't break a sweat. http://www.scintilla.org/SciTE.html http://www.scintilla.org/SciTE.html Bonus: you can use it in your own wxPython application. Some brave soul wrapped it and made available as wxStyledTextCtrl widget. http://www.yellowbrain.com/stc/index.html http://www.yellowbrain.com/stc/index.html BTW that's what I finished using for my app I mentioned in my other comment in this thread.
