I have a user that wishes to link (from a discussion / blog /wiki) to a document stored on a file server. We've tried creating a link, using the format file://server/volume/directory/filename.pdf, but clicking the link doesn't do anything. Hovering the mouse pointer over the link shows the correct syntax and link location in the browser's status bar, but right clicking and opening in a new tab/window results in a tab with "about:blank" in the address. Right clicking the link, selected "copy link address" and pasting the link address into a new browser tab works fine.

I've also tried linking to a folder on the file server, but that doesn't work either.

Linking to external web sites (http://server.domain) works fine, as you'd expect.

I've searched this forum, but not found anything. Am I missing something obvious, or is this not supported?
