Attachment delete link is off the page area on attachments page

I am uploading a video of this...when you go to an attachments page and see the list of attachments, the page always scrolls horizontally and the delete link is always off the white page no matter how much I enlarge the size of the window (so it's not a screen size) issue. The table does not resize it's columns properly to fit all content on the page.

This confuses users - they ask me all the time how do they delete an attachment because it is not obvious.

I am on mac, Safari, Confluence 5.4
