remote directory displayed as file

Using any protocol and either interface, my "public_html" directory shows up as a text file with a little shortcut arrow in the lower left-hand corner. The only way I can access the directory is to go to "Open directory/bookmark" and type in "public_html" after my root directory. Since it's now a bookmark, it's not hard to get to, but when I log in using another program, "public_html" displays like a normal directory. Any idea what could be going on here?
