This isn't a formal patch so much as a template correction.

Three lines in the post_attachmentbox template can be edited in the Admin Panel to prevent file selections from disappearing when the Multi-Attach link is used.

If this breaks anything that was working in less-common browsers, please let us know. It appears to work perfectly in the browsers I tried.
