I just upgraded my zenphoto to 1.1.4, found that at the sub album listing page, if one of sub album is password protectd, the listing will stop there and prompt for a password.

My temp solution is modify the checkforPassword function, if the parent album is not password protected or the parent album password is match the one enter, it skip the password prompt.

Thanks for the report. A fix will be in tonight's nightly build.
