Are you sure you inserted an animated GIF when you got the
automatically/when clicked option? Usually that only pops up when you insert
a movie -- Insert|Movies and Sounds|Movie from File.
Inserting a GIF is usually done via Insert|Picture. Animation or not has to
do with a combination of version of PPT and the GIF itself. See
http://www.soniacoleman.com/Tutorials/PowerPoint/animated_gifs/gifs.htm for
specifics.
