A hotfix (a TAR of files to upload) have been uploaded to this issue. These files are made to the latest intra-version state (i.e. may roll in earlier fixes too if made to the same files) - so only upload files newer than what you have already. Always take backups of files you are replacing or keep a copy of the manual installer for your version, and only apply fixes you need. These hotfixes are not necessarily reliable or well supported. Not sure how to extract TAR files to your Windows computer? Try 7-zip (http://www.7-zip.org/).

This hotfix caused me a problem with the box containing the social media buttons. After the update it extend to the bottom of the page. The solution drilled down to restoring the previous screen_actions.css although I do not know if the fix now works as a result of my action.

Thanks for sharing your experience. I've updated the file with a new screen_actions.css that I believe will fix it.

Some complex changes were needed due to how Facebook's own CSS works, and I believe the original hotfix was not compatible with all browsers.

That fixed it for me & Firefox 39.0, thanks Chris.
