All,
There is a bug in OpenOffice.org in version openoffice.org-1.1.0-15.EL where the help file doesn't open if you select help.
Here is the bug and the fix: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=122263
Basically, edit the file /usr/bin/ooffice and find <value>'$lang'</value> then replace it with <value>$lang</value>.
I have tested this on both CentOS and WhiteBox Enterprise Linux and the fix works.
This error has been corrected in FedoraCore with version openoffice.org-1.1.0-16. Supposedly to be released soon for RHEL...but if you can't wait, fix it now.
