[wxPython] Bugs/change in WxPython tutorial at O`Reilly ??

Hi,

Just started with wxPython and it looks promising. Tried the tutorial at www.oreilly.com but it didn`t work at all when I got into the middle of the article. Does anybody know if there has been changes in wxPython which makes the code used in the article useless?? I can post the code that casues the troubles later if needed. For now I just need to know if anybody has the same experience, or if anybody know a similar tutorial I can use to get started.

Thanks.
