Did some analysis on this issue. It only occurs if the first key after setting 
the column mode is the backspace key. If you have entered some text into the 
columns first and then press backspace it will work fine until the editing of 
that column is completed.

I am throwing the towel in on this for now as I am having difficulty 
understanding the contributed code that handles the column mode 
(src/extern/vert_edit.py). 

Cookie for anyone who wants to fix this otherwise I am going to wait till after 
wxPython2.9.2 is out and will work on a probable re-write using the new and 
improved version of Scintilla. Though will still need to support wxPython 2.8 
for at least another year or more so this module will still be relevant.
