frogtown on "[Plugin: WP-Filebase Download Manager] Post ID of the file browser being reset to 0 (zero)"

Occasionally, the "Post ID of the file browser" is being reset to 0. That of course causes the search function to no longer work. I'm using WP 4.1 and WP-Filebase 3.1.00.

Any thoughts on what would cause that?
