I had this issue before, with Browsing to spaces. That got fixed, but now I have an issue that the Browse button bumps me to the Log-in screen when I click either Blogs or Tags. Was this fixed in 1.0.4? I'm still on 1.0.3.
If you are being redirected to the login page, then the problem may be related to your user not having the proper security permissions. Can you log in as the administrator (for testing purposes), to see if the admin is redirected as well?
