I have a VFP 6.0 dbc with dbfs as the basis for a complex multiuser system
used by 10 operators at the same time. My client has also been using crystal
reports to run ad hoc reports on these tables. I took one of the dbfs out of
the dbc, modified the length of some fields, added several new fields
including some memo fields, then put the dbf back in the dbc, reindexed it
and packed it. The VFP multiuser system is running just like it always has.
However when the client trys to run one of his crystal reports he gets
'IDAPI Error: Corrupt Header'.

Any idea how the header could be corrupt for crystal but not for VFP itself?
