Mike, In older versions of MapInfo files on which MITAB is based, the REGION object could contain only a maximum of 32k segments, this would explain the problems that you encountered.
Someone wrote to this list a few months ago that this limit may have been increased in MapInfo V8, see the following bug report: http://bugzilla.maptools.org/show_bug.cgi?id=1496 If you (or someone else) can provide a sample MIF/MID with a REGION with more than 32k segments and the corresponding TAB dataset imported by MapInfo then we could use that to figure the new objects structure and add support for them.
