[Zope] "Zope DB instance has no attribute 'lock'"

[Derek Simkowiak]

	I installed the Z MySQL Database Adaptor product and configured a
connection with the simple 'database username password' connection string.
	
	Now I get the above when I try "select * from applicants" in the
'test' view of my database adaptor.  I have no idea what it means, or how
to troubleshoot it.  Is the problem in my database?  In Zope?  WTF?  The
database connections shows itself as 'open', so I think it can talk to the
database okay.

	What do I do next?  I'd post more information but I'm not sure
what information is necessary... Here is the traceback from the error 
message page's source HTML:

<!--

	...and some other stuff:

[dereks@dev dereks]$ rpm -qa | grep MySQL

[dereks@dev dereks]$ cat /usr/share/zope/lib/python/Products/ZMySQLDA/VERSION.txt

	Any help would be greatly appreciated.
