Friendly alias path is interferring with file paths from docs linked in TinyMCE

I have a site (MODx 1.0) in which I have FURL’s on and the Friendly alias path is set to "Yes". So everything works fine in regards to Resources showing up in the correct parent >> child relationship in the URL, (i.e. www.sitename.com/project/project-name.html). The problem is that when the client creates a link to a document (i.e. PDF doc) using TinyMCE, the link on the actual webpage includes the parent name in front of the file path to the doc. So for example, instead of the link being:

www.sitename.com/assets/files/doc-name.pdf

instead the page has:

www.sitename.com/project/assets/files/doc-name.pdf

When I turn off the Friendly alias path, the parent Resource no longer shows up in the file path. I set "Rewrite browser paths?" to "No" in Tools >> Configuration and still had the problem.

Anyone else had this problem before?
