Tabs appearing even though not selected
I have upgraded a project from SL2 to SL3. Now in both preview and publish versions, the 'Notes' tab (which I have renamed 'Audio') is appearing on all slides, even those where I have deselected them in the slide properties.
If I preview a single slide, the Audio tab is not appearing, but as soon as I preview /publish the whole scene or project, the tab is back again.
I have tried resetting each slide back to defaults, then selecting custom features again, with no luck.
Attached is a sample storyline file from the bigger project. The link for the published file is http://childcarecollege.com.au/learning/tabsissue/story_html5.html
