[Boa Constr] Error message when quitting Boa

[<ed....@nt...>]

Hi,

After playing aroud with different python versions and setups I've now settled down to 
using the following in Windows XP on an Athlon 1800+XP with 512 Megs of Ram.

Python 2.2.1
wxPython 2.3.2.1-Py22-Hybrid.exe
Boa-Constructor-0.1.0-alpha.Win32.exe

Problem:

Running Boa.py and all is fine until I exit.  [I haven't done anything with Boa yet!]
On exit I get the following error message: 

---------------------------------------------------------

Python.exe - Application Error
X The instructon at "0x00b576fe" referenced memory at "0x00000004"
The memory could not be "read".

Click OK to terminate the program
Click on CANCEL to debufg the program
OK CANCEL

-------------------------------------------------------

Any ideas?
