cannot save my Forum SettingsFollow

Forum Settings --> Posts per Page

I keep setting this to "100 posts per page" but when I click on another tab and return, this value has reset back to the default of "50 posts per page". The "Forum Settings" page does not have a "Save" button, so how do I tell your interface to remember the value I want for it to use, please?

Thanks,
Franklin

I still have this problem, same for filter setting too.

This fixed itself for me when I upgraded to the latest firefox for some reason. Unrated posts still need to be expanded, but that's rare and pretty much only applies to varus.
