It does (at least, the version I have does). It has

    def on_fldURL_keyPress(self, event):
        keyCode = event.keyCode
        target = event.target
        if keyCode == 13:
            self.on_goURL_command(None)
        else:
            event.skip()
which is why I mentioned typing a URL to it. Check if your 
sample/simpleBroswer has that too ....

Sounds right - it previously had "TextArea1" in it (from the resource 
definition), so when you hit BACKSPACE it should:
print the "point" to the console window
and then execute the keyPress handler, which says
   def on_TextField1_keyPress(self, event):
       print event.keyCode
       self.components.TextArea1.text = self.components.TextArea1.text + 
"%d\n" % (event.keyCode)

i.e. add the decimal value of the keyCode to the end of the text of 
TextArea1; BACKSPACE is ctrl-H == 8, so this is what I'd expect.  Note I 
didn't do an event.Skip() in on_TextField1_keyPress, so the key would 
not be passed through the usual processing.....

so (tentatively) I think the modified code is giving the right result.

I can't see what's different between that and what I quoted in the 
original mail
Could you change lines 335-341 of PythonCard/event.py  from

class KeyEvent(Event):
    def decorate(self, aWxEvent, source):
        aWxEvent = Event.decorate(self, aWxEvent, source)
                # this is basically the same block as MouseEvent.decorate
        # but it seems wrong to have KeyEvent be a subclass of MouseEvent
        aWxEvent.position = tuple(aWxEvent.GetPosition()) 
(I only listed lines 335 to 341 - so apart from funny indentation of the 
comment, it looks the same as what you have).

Perhaps just the confusion of line-wrapping in email ?

As I said above - it looks as though it's working  for you 0.8.1, so 
unless you run into a problem, you may be able to stick with 0.8.1

(0.8.2 may be only in CVS)

We should make sure we get that fix incorporated - but maybe we'll let 
it sit until you have another week or two's experience, in case you run 
into anything else ....
