If you are using the example from the download page exactly, remove this from the events
onloadcomplete="intro();"
In other words, go from this
<events onloadcomplete="intro();"
onmousedown="set(autorotate.enabled,false);"
/>
to this
<events onmousedown="set(autorotate.enabled,false);"
/>
or
<events onloadcomplete=""
onmousedown="set(autorotate.enabled,false);"
/>
On another note,
If you never want to use this action again like putting in your own text, also remove this code from the fireworks.xml
Edit: remove from pano.xml
<action name="intro">
set(autorotate.enabled,true);
set(autorotate.waittime,2);
set(autorotate.accel,0.6);
set(autorotate.speed,1.5);
set(autorotate.horizon,-12);
set(autorotate.tofov,90);
delayedcall(1, showtext('
krpano'); );
delayedcall(4, showtext('wishes you', SMALL); );
delayedcall(7, showtext('A Merry Christmas'); );
delayedcall(10, showtext('and a', SMALL); );
delayedcall(13, set(textstyle[DEFAULT].fadeintime,2);
set(textstyle[DEFAULT].showtime,10);
set(textstyle[DEFAULT].fadetime,3);
set(textstyle[DEFAULT].fontsize,50);
showtext('Happy New Year');
);
</action>
