Hi,
onexitfullscreen="set(plugin[fullscreen].visible, true);
set(plugin[txt_presentation_deux].visible, false);
flyout(get(name));"
The get(name) is wrong here - you need to enter there the name of the hotspot!
Additionally there is a closing " missing at the end.
And I'm not sure if you want it that way - but this 'flyout' action code makes the 'flying' hotspot back to normal - in the example from where you had this code were was also a 'flyin' action that makes the hotspot flying. That 'flyout' action here can be used only when the 'flyin' action was used before.
Best regards,
Klaus
