Hi Wayne,
I did as you suggested, and here is the output:
>>> *********************
HERE10 ('http',
'//mole.bio.cam.ac.uk/~ccpn/ccpNmrUpdate/__UpdateAgentData.db')
HERE11 {'http': 'http://'}
HERE12 http://
HERE13 ('http', '//')
HERE14 ('', '')
HERE3 ('', '
http://mole.bio.cam.ac.uk/~ccpn/ccpNmrUpdate/__UpdateAgentData.db')
HERE4
Exception in Tkinter callback
Traceback (most recent call last):
File "/sw/lib/python2.5/lib-tk/Tkinter.py", line 1403, in __call__
return self.func(*args)
(...etc...)
Hope that gives some clue.
-Jeremy
