I haven't installed wxPython 2.8.x on any boxes so the following  
suggestions are untested but it should get you going in the right  
direction.

The MultipleChoiceDialog is defined in wxPython, not wxWidgets, so it  
should be relatively simple to fix this for your code, though you may  
end up duplicating a lot of the underlying wxPython code and need to  
add an if/then block to use the old code if running wxPython 2.6.x or  
earlier.

PythonCard defines an alias to the wxPython dialog in PythonCard/ 
dialog.py with the following bits of code:

import wx
from wx.lib import dialogs

...

multipleChoiceDialog = dialogs.multipleChoiceDialog

As you can see from the import above you want to look at the wx/lib/ 
dialogs.py file for the code that needs to be tweaked for wxPython  
2.8. What you want to do is make your own multipleChoiceDialog and  
use that if wxPython version is 2.8 or higher. Something like:

if wx.VERSION >= (2, 8):
	multipleChoiceDialog = # your definition here

# in the rest of your code use multipleChoiceDialog instead of  
dialog.multipleChoiceDialog

If in fact they replaced ListBox with CheckListBox, that seems like a  
bug to me since they shouldn't have kept the same id if the  
underlying functionality was going to change. But even so, the old  
ListBox should still be available, you just need to figure out the id/ 
name and substitute that for the CheckListBox where the wxPython  
makes use of it.
