I don't think you can expect that an Access runtime 2010 can
handle an access 2003 application. That's not very likely.

Yes.
I tested this result also with an C programm and yes indeed it is 53 and
this is wront. It probably is the number of bit sin the mantissa of a
Double.
A work around may be not to use this query of the column but "hack" it
that it just picks 15 bytes. I guess it tries to load all the 53 bits
and well, who knows what bits pattern there may be around a Double...
Hardly anything meaningful.
