thanx for clearing up east-west filing oversight. many individual filers file wrong or they forget. very common. this is largest corporate memory loss i've seen (nearly 5M shares) but can well believe it happened just so. as i wrote there seemed to be no advantage whatsoever to delay the reportage.
re takeover: your train of thought is good. no control so why worry. if the possibility makes someone desperately unhappy he should not be in small explorers these days anyhow.
