Cosmin, The UNAVCO plugin may be giving you trouble. Please delete the UNAVCO plugin in /home/cosmin/.unidata/idv/DefaultIdv/plugins/ Alternatively, you can move your ~/.unidata directory (i.e., mv .unidata unidata.bak), and restart the IDV. In order to reinstall the UNAVCO plugin please run the following command. ./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.
