Troubleshooting the Jazz Web Interface.

I am writing a training module on troubleshooting Jazz. I am currently
on the web section and was using Firebug to gather the debug messages
from Dojo. I noticed this:

"failed to find module in module graphdojo.js (line 376)
failed to find module in module graphdojo.js
(line 376)
failed to find module in module
graphdojo.js (line 376)
failed to find module
in
module graphdojo.js (line 376)
failed to find module

in module graph"

The Firefox 3 Error Console list several CSS entries similar to :

Warning: Unknown property 'zoom'. Declaration dropped.
Source File: https://jazz.net/jazz/web/style.css?ver=4205887457
Line: 147

I assume these debug messages are expected. If so, what type of messages
should we expect vs. what type of messages should we be concerned about?

Thanks!
