[Rails] [Error] path not found

[boonhoo]

Hi, lately I find that my rails server on winxp desktop seems erratic.
Sometimes when I access my sample applications from the tutorials
(especially those that use login redirection),  rails will return a
Not found error, e.g. '/weblog' not found..  Only after restarting the
server and reopening new browser instance, I can access rails again.

also I noticed that, whenever I access a page and close my browser,
the following errors will appear:
[2005-02-17 23:26:31] ERROR Errno::EINVAL: Invalid argument
        g:/tools/ruby/lib/ruby/1.8/webrick/httprequest.rb:325:in `gets'
        g:/tools/ruby/lib/ruby/1.8/webrick/httprequest.rb:325:in `__send__'
        g:/tools/ruby/lib/ruby/1.8/webrick/httprequest.rb:325:in `_read_data'
        g:/tools/ruby/lib/ruby/1.8/webrick/httprequest.rb:324:in `timeout'
        g:/tools/ruby/lib/ruby/1.8/timeout.rb:55:in `timeout'

anyone faced this problem on winxp? could it be sesison problem?

below are the gems i have:
actionmailer (0.6.1)
actionpack (1.4.0)
activerecord (1.6.0)
fxruby (1.2.2)
rails (0.9.5, 0.9.4.1)
