---------------------------------------------------------

I understood that this JDK was likely to be completely untested with Cayenne, 
the 1.6 version, especially, as it is brand new.  And yes, it's clearly a 
problem with the Swing stuff.  Unfortunately, this JDK is my best option on 
this machine, a Powerbook running Linux, as Sun does not support Linux/PPC.  It 
has been great for the most part, however, and I expect that there may be a 
fix/workaround for this issue.  Perhaps it's simply a matter of specifying a 
certain configuration option.  Below is the output of of 'java -version', and I 
will also downgrade to the IBM 1.5 JDK and check that out, too.
