Summary: Browser.js Recommended Upgrade
Initial Comment:
The following is a recommendation for changing the
Browser.js code. This should fix several bugs which
currently exist which affect the detection of Opera,
MSIE, win32, and mac systems. It would obviously
require making changes throughout the API system due
to changes being made in variables.
