I just installed 1.6-alpha the other day and it seems to require a login/password way too often.

When I save a blog entry, I'll find I've been logged out and have to log in again to do any editing

To get around being logged out when I clicked Save, I tried clicking "Exit to blogs", thinking that would leave me logged in. It does, but when I edit an entry and try to save the changes, if there's an error in the HTML that requires me to go back to the post to fix it, I get caught in a loop:

The Login window appears, then when I've logged back in, I can't use the browser's Back button or the [Back to post editing] link to return to the post to edit the code because the login window keep appearing. I then have to start over and lose the changes. Each time this happens (three times this morning!), the follow-on attempt to edit a post succeeds.

Is there a setting I can adjust to limit how often the Login window appears? And what's causing the loop problem?

Thanks,
Chris
