logging out problems

one, i would like to say that webpress has been the easiest installation ever! in any platform!
two, now to my problems:
1. whenever i want to log out, the address duplicates itself
ex.
http://otter.fivio.com/ramble/wp-admin/b2edit.php :: this is the original address prior to logging out
http://otter.fivio.com/ramble/wp-admin/otter.fivio.com/ramble/b2login.php?action=logout :: this is when i clicked the logout button
any inkling to the problems?
2. does the basic installation of WordPress includes a ccs file? as my website is like, not what featured in the opensourcecms.org (sp?)
thank you
