I was looking for a reason why sometimes a window won't close. Example after writing and sending an email, the window stays open. Searching through the Jetty logs I find a lot of these:

[19/Feb/2009:14:20:22 -0500] "POST /service/soap/NoOpRequest HTTP/1.1" 200 702 "https://mail.mbl.edu/zimbra/" "Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv: Gecko/2009011912 Firefox/3.0.6"

Are these normal??
