I have a website in a directory on my hard drive. I’ve attached a link to the index.html file to an entry in Zotero. It opens up fine (mostly), showing images properly, and with the external links working fine. However, *internal* links, to other pages in that directory, do nothing, making the whole procedure pretty pointless.

Is there a way to fix this, or, barring that, a way to convince Zotero to always open that file in an external browser?
