"how the scans were switched...?"

Too many previews...

I learned the hard way that after you load a buncha' scans (using the awesome "browse" button) and preview your post several times before posting it, the gremlins sometimes come in and switch your scans with someone else's...

I wouldn't have realized how it happened to me, except that I remembered someone else (Gene?) muttering about it, when it happened to him!
