Cannot get NAV to run when clicking the System Tray icon (get hourglass for a second or 2 and it disappears). Ditto when clicking the Systemworks icon on the Desktop. Yet, I know that everything is working fine when sending and receiving Emails, plus all programs will execute when selected via Explorer or if set up to run via Task Manager – weird as heck! There are no viruses (as suggested by the Knowledgebase article) as the system was cleansed prior to installation with AVG, Spybot, HijackThis,etc., and Rnav2003 and symclean were used to ensure complete uninstall + used RegLite to delete every existence of Symantec and Norton keys/values in the Registry. Any ideas???
