+ \item When using AppImage to run with the OpenGL video driver, you must have the OpenGL drivers
+for your Operating System graphics board installed as it is not included in the AppImage library set. The
+error message you might see if this is not installed is: \textit{error while loading shared libraries: libGLU.so.1: cannot open shared object: No such file or directory}.
+ \item If you have updated your Operating System or newly installed some applications, it is
+possible that your LV2 plugin path may have been modified and be in disagreement with what you have set
+for \CGG{}. This could result in a crash upon startup. Look at the messages in the window from where
+you started \CGG{} to see if they look similiar to the following:
+\begin{lstlisting}[numbers=none,xleftmargin=10mm]
+LOAD: http://eq10q.sourceforge.net/matrix\_lr2ms
+LOAD: http://eq10q.sourceforge.net/matrix\_ms2lr
+LOAD: https://community.ardour.org/node/7596
+LOAD: urna-comp
+** segv at 0x7f2cd80813c4 in pid 4540, tid 4540
+\end{lstlisting}
+The last line before the \textit{segv} indicates the name of the LV2 plugin that is causing problems.
+Please refer to the section on LV2 plugins \ref{sec:audio_lv2_calf_plugins} to resolve the issue.
+ \item Check your \textit{Overlays} window if you do not see your Assets, Titles, Transitions, Plugin Keyframes, or other lines such as Fade, Cameras, etc. on your timeline.
+These items will still be functional, but you may be confused when you do not actually see their physical presence if you inadvertently unchecked them in the \textit{Overlays} window. Use the \textit{Window} pulldown to enable/disable the \textit{Show Overlays} window.
+ \item BugTracker - sometimes there is a problem creating a new report issue in the website's Mantis Bugtracker
+using the Chrome web browser and you lose what you just typed in. Generally when logging into the bugtracker, the
+option "only allow with this IP address" needs to be disabled, then the bug tracker will work fine.
+ \item Forum -
+
+ \begin{enumerate}
+ \item If you can not register your username in the website's Forum, it could be
+because the protection measures against spammers also is in effect with real users, so sometimes the website blocks the registration for the forum. This often affects email addresses of well-known email providers. Send email to the mailing list (({\small \url{https://lists.cinelerra-gg.org/mailman/listinfo/cin}}) so that you can be added to the forum manually as long as
+you confirm that you agree with the terms of use of this website and the forum.
+ \item In the website's Forum, use of unacceptable characters or strings can result in the error
+message "A potentially unsafe operation has been detected in your request to this site". You lose what
+you had typed in and you will have to check what you remember typing in for a non-converational set of
+characters. This can be as simple as ../../ (dot dot slash dot dot slash) or some types of C++ code.
+
+ \item Entries not showing up for several hours could be due to taking a long time
+to propagate around the world on some time basis.
+ \item Not seeing a comment or reply section could be because you are not logged in
+or recognized as logged in. If you seem to be logged in, logout and then login again to
+see if that resolves the problem.
+ \item Until you have made a few entries in the Forum, you will have to wait a few
+hours for your entry to be approved. This is because there are people who spam the
+forum so attempts to alleviate this by requiring moderation for new users until validated.
+ \end{enumerate}
