If I have a couple of attachments in a log book entry, I can link to that entry "http://example.edu/elog/Sandbox/7", I get the appropriate log in page, and after logging it, it takes me to the entry.

However, if I link directly an attachment, "http://example.edu/elog/Sandbox/7/1", I receive a plain log in page that doesn't have the stylesheet applied, and logging in, I am directed to " http://example.edu/elog/Sandbox/7/" which throws an invalid error. If I am already logged in the browser, it links correctly. 

I assume the problem must stem from messed up relative URL somewhere, hence the lack of stylesheet, or from the redirect incorrectly handling the /. (Looking at the source for the two login pages, the only difference is "<input type=hidden name=redir value="7">" versus "<input type=hidden name=redir value="7/1">". ) But that reaches the end of my ability...

This breaks the attachment links in emails.

Any help would be much appreciated!
