<BODY>
<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I recently updated from wxPython 2.8.4.0 to 2.8.4.2 on my Mac, using the binaries supplied at the wxPython site.<BR>
<BR>
After updating, wxgrass crashed with the error listed below. After I uninstalled 2.8.4.2 and reinstalled 2.8.4.0, it runs fine.<BR>
<BR>
I've posted this to the wxPython bug list too.<BR>
