Did Adobe change something on their web site that broke FM10 help? Maybe it's not just FM10?
I just did Help > Help Topics and searched for "change bars" with "This reference only" selected. Cold Fusion or whatever replaced the quotes and space with escaped HTML and the search found no results. http://www.adobe.com/cfusion/search/index.cfm?cat=support&term=%2522change%2520bars%2522&loc=en_US&self=1&lr=en_US&site=framemaker_10_all
