I have noticed that both Internet Explorer and Mozilla Firefox report a synyax error when I use these browsers to look at the client_state.xml file (I have removed the angle-brackets so the msg will print):

XML Parsing Error: mismatched tag. Expected: /file_signature.
Location: file:///H:/Program%20Files/Apps/BOINC/client_state.xml
Line Number 94, Column 7:
/signed_xml
------^

I don\'t know if this is a genuine error, but I\'ll report it anyway, since I have not seen this with any other Boinc projects.

BOINC does not always use standard xml format, however that particular one does look like a real problem.

yep, the xml is invalid:

it doesn't seem to affect boinc though.
