I am getting the "No Valid LangCat Object" in my iTools display. The LangCat files are in their correct folders. I believe I have a problem with the path. I am trying to resolve this using the suggested support page on this website. The command box currently reads:"IDL> print,pref_get('idl_path') IDL_PATH>;IDL_PATH>;IDL_DEFAULT>"When it should be reading this:"IDL> print, pref_get('idl_path')IDL_DEFAULT>;C:\Exelis\se51\lib;C:\Users\username\dj_dialog_editor;"...obviously I am missing this entire part of the path "C:\Exelis\se51\lib;C:\Users\username\dj_dialog_editor;" Does anybody know how to resolve this problem?
