Claes,
Here's how you do it.
1. Open the table in MapInfo. And note the projection of the table (Map >
Options > Projection)
2. Choose from the menu Table > Export to export the table as a DXF file.
3. Change the Save File as Type box to AutoCAD DXF (*.dxf)
4. Choose the location to save the DXF file
5. In the DXF Export Information dialog box, Uncheck "Preserve Multi-Polygon
Regions
as DXF Blocks", Check "Preserve Attribute Data". Click OK
6. Choose from the menu Table > Import
7. Change the File as Type box to AutoCAD DXF (*.dxf)
8. Choose the location of the file, click Open
9. Check "Preserve Attribute Data", Uncheck "Preserve Multi-Polygon Regions
as DXF Blocks", Choose the projection of the file.
You should now have a table containing the multi polygon objects broken down
into separate objects.
Hope this helps,

Subject: MI Uncombine polygons
It is easy to combine polygons, for example a group of islands, to a region
in Mapinfo.
But how to split them again to individual polygons using a field in the
database.
I know how to divide them graphically, but I need to do it in one stroke.
I.E the opposite of "Combine objects by Column".
The only way I found out is to export them ti MIF and edit the MIF/MID
files.
Not very fun i you have many polygon groups.
