OOo Base: User not found (Error code -37)

Hi,

The problem comes from a conflict with an old hsqldb Java library.
OpenOffice Base seems to work properly after removing this oldest library.

Bye,
Henri.

PS About zip files in my first email:
These are backups of my working directory.
Db1.zip contents the file Mes documents\Db\Test.odb
Db2.zip contents the files Mes documents\Db\Test.odb, Mes 
documents\Db\Test.data, Mes documents\Db\Test.properties and Mes 
documents\Db\Test.script
They were zipped using the standard tool of Windows XP.
