While playing around (painfully) with yesterday's breed standard documents, came across an interesting message:
What's FBviewer.exe? Just some random file in my ~/Downloads directory, it seems. Potentially it is dangerous, and I just had it there (safely in FreeBSD) for examination. So I clicked Move to Vault, whatever that means, and it's now off dereel and (presumably) somewhere on braindeath, which is no safer for it.
