When we get an EIB_Error "Invalid Filter Syntax", it causes a strange
problem for us. The table is still active, but no longer will display in
Delphi controls (eg, TDBEdit fields). We apply filters to move the
database cursor and that seems to work (except we can't see the actual data
because it won't display).

What do we need to do to the table to get it back operational again? What
test can we make to determine if it is in this particular state?

We can create this problem at will by having an apostrophe in the filter
(we haven't fixed the problem because we want to use it as a test for when
we find out how to fix the table).
