After nearly completing the thunderbird download,the download manager indicated a "cancelled" message with the note that the file could be saved to disk,which I promptly did.I have been unable to install the program normally by using the recommended commands as I get "a no file present" message.However, upon checking in my home file under thunderbird,I can launch the program by double clicking on the 6.5k shell script file then selecting "run".Each time I launch the program I have to go to/home/William/wwj/thunderbird/then double click and run the 6.5 shell script file.Is there an easy solution to resolving this? Or should I delete the file and redo the download using apt-get? As a "Windows" user I have easily moved to Fedora C1 but know nothing about its inner workings as indicated above. Thanks for any advise. Bill
