Closing "Recently viewed" sidebar

I have a fresh bitnami stack installation of 7.1.5 that I upgraded to 7.2.1 and swithced to the responsive theme. Unlike my production version of 7.2, there is no tab to hide the sidebar. Any suggestions?

Quick Repair & Rebuild in Admin -> Repair, clear your browser cache.

What resolution are you viewing the CRM on?

It could be that it’s at the resolution where the sidebar is disabled.

Thanks,

Will.

Thanks, but the problem persists. The resolution is 1280x800. I have a production instance of suitecrm 7.2 running on a different server and it displays fine on this monitor. The two servers are both ubuntu server 12.04 LTS and both are stacks.
