Dear Richard, In the version 3 bigWigs there was a bug in the way that the summary information was kept. The bug was fixed in version 4 bigWigs. There is also a magic number at the the end of v4 files so that they can be checked for truncation.
If you have further questions, please don't hesitate to contact the mailing list.
