Hi Graham,
Faced with a similar problem recently, I found a free program called "Poly Plus" for
decombining MapInfo objects. The software worked well for what we had to do (ie: split
these combined polygons so that in the resulting table every record in the table
represents a single geometric shape).
I found the software at http://www.spatialplus.com
I hope this helps

Subject: MI Splitting polygons
Hi everyone,
I have a MapInfo layer containing a large number of records. Most of the
records are single geometric shapes (polygons), but some are comprised of
geographically separate polygons that have been combined into a single
record. I need to be able to split these combined polygons so that in the
resulting table every record in the table represents a single geometric
shape (polygon).
Does anyone know how this can be done automatically using mapbasic? I
know that it can be done interactively, by drawing a shape around a polygon
in the cosmetic layer and using the "Split" command, but I have around
50,000 records in the table and it would take forever to do this manually.
Is there some way of identifying from the .MAP file whether a record
consists of more than one polygon?
