Yves,

Thank you for your response. It is a lot of work for
us to "try the latest release" since we have a product
that adds a lot of stuff to Jigsaw and every new version
is usually a several day porting effort.

If you have some specific things that changed to address
the problem I mentioned it might be easier for me to
back fit the changes to 2.0.3 which is the latest version
we're running under.

Thanks in advance for your comments. Being very specific
would be helpful.

Dwayne
