I am experiencing the same problems (slow, unresponsive) as mentioned above since Ubuntu 12.04 and Zim 0.56. I sometimes even have to go in system monitor - processes to kill the Zim process before I can start using it again.
Also like the earlier reports, I am only experiencing this problem with ZIM.
