Have tested on old documents as well. When I click on Preview, it shows for a few seconds then disappears.
On which environment are you ? (Windows, Linux, MacOs) If Linux, which distribution ? Just in case you would be on Ubuntu, if you have lo-menubar installed, could you try again with lo-menubar uninstalled ?
Distro: Ubuntu 12.04 (up to date) I have removed the lo-menu extension, and this seems to have resolved the problem. "Resolved" the missing freeze problem as well. Thank you. How does one add a warning / comment to Software Centre?
Found the other bug about this so I update the status to dup. *** This bug has been marked as a duplicate of bug 50197 ***
