Tim, We believe it is the UNAVCO plugin giving you trouble. In order to install the UNAVCO plugin please run the following command. /Applications/IDV_5.0u1/runIDV -installplugin http://www.unavco.org/software/visualization/idv/unavcoidv.jar In future versions of the IDV, you will also be able to install this plugin via the plugin manager. (We had the wrong location for the plugin internally within the IDV.) Let us know if you run into problem.
