When I run your application everything appears to work fine.
If I expand all nodes then I go through 0-a-2183, 0-a-2184, 0-b-0, 0-b-1,
...
If I then collapse item 0-b the cursor moves from 0-b upwards to 0-a-2184,
0-a-2183, ... and downwards to 0-b, 1, 1-a, ...
Is this what you were expecting, or do you want the tree to expand
autamatically as you move through it with the arrow keys.
I'm using Windows 2000 with Python 2.2 and wxPython 2.3.3pre3.
regards
Steve

I tried your example on Win98SE, Python 1.5.2, wxPython 2.3.2.1 and on Mandrake Linux, Python 2.1, wxPython 2.3.2.1, wxGTK 2.3.2-1.
On Windows, it seemed to work fine. The last sub-sub-item in 0-a is 2184, and pressing down moves to 0-b.
On Linux, the OnSelChanged text in the right panel indicates the same behaviour. However, the display of the tree scrolls back to the beginning when I try to hit down from 0-a-1817 to get to 0-a-1818. Nor can I use the scrollbar to manually display the rest of the tree below 0-a-1818. The right panel still says that 0-a-1818 is selected (correctly). Is that what you meant when you said "it wraps to the beginning of the list"?
Also, there are numerous other problems with the display of the tree. For example, if you expand 0-b and then 0-a, the contents of 0-a are obscured by 0-b-1454, 1455, ...
Not sure why this happens.
