Hello,

I have a small database requirement so instead of SQLite I am using a simple
DataSet.  I have a schema as a resource of my application and then I just do a
WriteXML (ExcludeSchema) and ReadXML so I'm only reading/writing the data and
not bloating the file output with the schema.

I've had problems since day one with data just disappearing.  I don't know what
the cause is, I've had product update after update trying to rectify this,
today I'm starting a migration to SQLite as I cannot trust the DataSet methods
any longer.

A few releases ago I built in an exception logger and I've related the
following error message to the problem.  It appears your XmlReader may have an
issue with end of file problems, maybe due to an encoding or format issue on
the Apple platform?  Here is the error message logged:
