I'm recently using Boa Constructor to build GUI, and here's my problem:

create a new wx.Frame
add a wx.Panel
add a wx.BoxSizer
add a wx.StaticBox
add a wx.StaticBoxSizer

It crashes every single time and I've no idea why? Am I doing something wrong?
Environment: win 7 Ultimate 64bit / python 2.7.3(32bit) / wxPython 2.8.12.1 / Boa Constructor 0.6.1
Found the problem:
Boa Constructor always automatically add wx.StaticBox into previous wx.BoxSizer you created on wx.Panel, and you have to remove wx.StaticBox from wx.BoxSizer before you add wx.StaticBoxSizer for wx.StaticBox, or the whole program would crash.
Boa Constructor keeps crashing
