I am able to create a user account with no issues, but when I click the Account Login button, I get the following error under Firefox 2.0:

XML Parsing Error: not well-formed
Location: http://localhost:8080/seam-booking/main.seam?cid=9
Line Number 76, Column 9:<!DOCTYPE div PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
--------^

However, the same page (and the rest of the app) works without a hitch in IE7.

Does anyone have a workaround for this?

Thanks.
Ian
