Andreas,

I would have no objection to adding a layer creation option
which would disable the bounds.  Do you have any idea
why the bounds are causing the import into mapinfo to fail?
Does your data fall outside the indicated bounds?

Re-reading your message I get the impression that dropping
it just improves the precision the data is imported with in
MapInfo, is that right?

Best regards,
