1)The SQL Server mobile software is installed on the internal memory
of the mobile device.
2)The DB is located on an SD Memory (external memory)
on a Datalogic Memor Device.

When i don't use the application for some days,the
software "SQL MOBILE " crash,and i must reinstall the
software.
When the user quit of the application,the connection with the
DB is closed.Have you the same problem?
Can you help me?
