I tried to reproduce this bug but it seems fixed.

Comments:	Lets see. First disconnect computer from network, then start
squeak,  
then do help->update code from server
which then attempts to resolve the squeak public server name, which of  
course is going to fail, however now
we get an unexpected failure of a different sort since when we execute:

(NameLookupFailure hostName: hostName) signal: 'Could not resolve the  
server named: ', hostName

with the response choice of Give Up or Retry.
and I
Pick Retry.

handlerContext is nil, so we get a "does not understand..."
Anyone care to fix this?
