<p>My corporate firewall blocks browsers other than IE. I found a workaround to still being able to use my favorite browser by changing its user agent. But now, the AJAX version of the demo application does not work.</p>

The WingS framework (AJAX UI layer of Jspresso) uses the browser user agent (identifier) to cope with the differences in JavaScript support. Changing the browser user agent makes it recieve inapropriate JavaScript code and generates unexpected results.
