When the Acajoom newsletter is detected the editor goes into inline style-mode; this is used to carry forward newsletter styles across to the mail recipient that would otherwise be lost. It was found that in certain instances, the editor froze on initialization because of an issue with  the translation of quoted font names into inline-styles. We are please to announce a patch that  will address this issue for Joomla! 1.5 when the following occurs: Acajoom + JoomlaFCK +  rhuk_milkyway, pinboard template (possibly others...).

Instruction: Please note that you do not need to upload the files via FTP, the fix can be applied by installing it via the Joomla administrational backend. If you haven’t already installed version 2.6.4.1 you will need to do so before you install the upgrade patch.
