What a List is the Fedora List. When I got on it I was having a big problem of some sort. In a day or two the problem was gone. It has been this way to today.
I was having trouble getting the old select the words with the right mouse button, go to another place and with both right and left buttons closed what you selected is where you want it. One member asked me if /etc/X11/xorg.conf file had the emulate 3rd button with a yes or no. It needs to be yes. I fixed all three systems and now this feature again works. I bought a new keyboard and was worried I would just have to get another computer. But now I know there is nothing wrong with this one thanks to this List.
A sudden change in my Thunderbird email system was a big problem. I was swatting bugs on the Muzzila web page and then learned from the list I had un-checked a critical part of the setup. It is always checked on a new system. It is View -> Layout -> Message Panel, and that produces a space below the messages where you can open them. And you can make the space for old messages small. This solved the Thunderbird problem.
Now I know a lot more, and more important I know what I don't know about Fedora. I want to thank you all for your help. I would be using a new computer for no valid reason, and using another type of Linux and having the same exact problems without your help.
