Okay, makes sense.

Oddly, though, I'm still getting garbage icons. Sometimes it's the one-dot, sometimes it's the garbage icon. It's intermittent.

edit: and let me re-iterate that I do not get these garbage icons when I go to my FTP site at my ISP. I get the full explorer-style folder treatment but without either a single-dot nor a double-dot icon, and without the garbage icons.
