Just to be sure, do you expect the second link (in a browser) to show "Error
handling request: no current query"? This seems to work w/Python 2.2 under
cygwin, at least. There was so much output I omitted quite a lot, replaced
by ellipses below:

>>> import urllib
>>> f =
urllib.urlopen("""http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Display&
db=PubMed&details_term=%28%22glucagon%22%5BMeSH%20Terms%5D%20OR%20glucagon%5
BText%20Word%5D%29&dopt=XML&query_key=1""")
>>> ll  = f.read()
>>> ll
'<html>\n  <head> ...
<table
cellpadding="0" cellspacing="0" width="100%"><tr><td bgcolor="#ffcccc">Error
handling request: no current query<BR></td></tr></table> ...
</body>\n</html>\n'
>>>

 Steve
