Running latest ZCS on Ubuntu 10.04.2 LTS, for some reason the reading pane view setting does not "stick" for any of our users. Most of them prefer it on the right, but every time they login it's reset to the bottom.

Interestingly enough, we have another server with the same version of Zimbra on Debian 5 and the setting works fine.

Has anyone run into this and knows how to fix it?
