Maybe some labels and some instructions for how to use it. I can't say it has a friendly interface.

Um, what does that mean? I find your comments very bizzare

Interface is fairly standard, you click on stuff until you see something interesting ;) click on list items, select from dropdown menu, type in textbox...

I see now, the problem seems to be that it behaves differently with "Wx Version: 0.9918 wxWidgets 2.8.12", the Method list is empty from start, but works better with "Wx Version: 0,9918 wxWidgets 2.9.4. (Citrus Perl)".

Hmm, for me it behaves exactly the same on both :/

Maybe only the Classes list is not what it should be, it's filled with "W" and "W.".

you can add  $classes_listview->SetColumnWidth(0, 3000 ); for that
