Okay, back up and running, thank $DEITY for recordable DVD's....

Now, I have a problem with 0.7.3 when running with python 2.2.2 and wxPython 
2.5. I've installed 0.7.3 from the tarball and wxPython from the RPM on 
wxpython.org.

When I run the resource editor from a command line prompt, I get this:

The problem is that at line 309 (line 316 in the code below) of menu.py, the 
value of 'id' is set to -1 when it tries to call self.Enable(). As far as I 
can see, the code in this part of menu.py hasn't changed between 0.7.2 and 
0.7.3, so I'm stumped as to what's going on. I put a bunch of print 
statements into menu.py so it looks like this:

299    def setEnabled( self, aString, aBoolean=1) :
300        print 'setEnabled, aString = [%s], aBoolean = [%s]' % (aString, 
aBoolean)
301        i = 0
302        for m in self.menus:
303            print 'm is now [%s]' % m
304            menuLabel = m.label.strip('&')
305            print 'm.label = [%s], menuLabel = [%s]' % (m.label, menuLabel)
306            if m.name == aString:
307                print 'm.name == aString'
308                self.EnableTop(i, aBoolean)
309                break
310            for mi in m.items:
311                print 'mi is now [%s]' % mi
312                if mi.name == aString:
313                    print 'mi.name == aString, menuLabel = [%s]' % 
menuLabel
314                    id = self.FindMenuItem(menuLabel, mi.label)
315                    print 'found menu id [%s]' % id
316                    self.Enable(id, aBoolean)
317                    break
318            i += 1

When I run with this code, my output is:

I've tried some of the other samples (proof, addresses, etc) and these run 
without any problems, it looks like its just the resource editor in this 
case.
