Invisible desktop icons, name still visible
After upgrading to Lion (10.7.3), after thorough software updates, repairing permissions several times, logging in and out, and generally using it on a regular basis for a few days, I still occasionally get some invisible desktop icons. This never happened before in Snow Leopard on back. I keep about 20 items on my desktop — hard drives, aliases of folders, aliases of files, a few textedit files. When I login, sometimes everything is fine. But sometimes two or three icons would be invisible. Their names would still be visible. It's not always the same icons. It's random and intermittent.
When invisible, I cannot select them by direct clicking, but only by surrounding it with a marquee selection (dragging a box around them). I can change their name.
Is this a known bug? Any fix?
