Thanks for the help. I got it working. The first thing I did was replace Ubuntu with Open SUSE 11.1 (with a disc from Linux Format magazine). After getting that running and updated I downloaded the rpm package from the Serna web site. I think my problem before was that in the download manager in Ubuntu I let the archive manager open the download. In Open SUSE the default is to open with the package installer and that worked. I think if I had changed the opening software under Ubuntu's download manager, it may have worked. I'm letting my newness show, I didn't think to change from the defaults in Ubuntu. When I got the software installed first off I looked for it in the Application Browser, not there. Next I checked in the Software Manager, there it was. It took a little scouting around but I found the serna.sh file under usr/local/serna-4.1/bin. I double clicked it and there was the editor. Yea!
I copied the serna.sh file to the desktop and it works fine. I would like to get Serna to show up in the Applications Browser just like regular installed applications, how do I do that?
