Verified on 13x nightly that the instructor can successfully add an attachment to student response.  When feedback options are set, student can successfully view the attachment.

Okay this seems to have fixed it in our instance:

I'd like to add that this seems to be failing with FireFox and Chrome, but it works as expected in IE.  So this seems to be a browser related issue.

There are a few places where Add Attachments button appears, and it works in 3/4:

1. Scores > Questions (works here)

2. Scores > Total Scores (works here)

3. Scores > select student (doesn't work)

4. User Activity Report > select student > select submission (doesn't work).

Additionally, for the views (#3, 4) of individual student's submission, there is no Add Attachments button at the assessment level (under text box at top of page) - this needs to be added for consistency.
