open office base

[michael miller]

Any suggestions on reference material for open office base?  I've read
the open office 3 guide and a couple of on line tutorials which cover
the basics.  Nothing that tells me how to deal with the nonspecific
often nonfatal error messages that pop up or help me understand how
things really work.  Is there enough functional overlap that books on
non-OO data bases would be useful?

Thanks
