If you require "SEARCH" to work then stay with the previous version. The current version, 4.2.0.2 has a bug that won't display the search option. Changing back to the previous .jar file did not work (as suggested by MacJuanC in an earlier post here at VersionTracker).

If you want to upgrade - best to use the method MacJuanC has detailed below - it will give you the new features without the additional baggage (and without search facility!).
