I'm having a similar issue with a spinning cursor as mentioned in the previous posts, dated several years ago. When I preview or publish a course, some slides display a spinning cursor, which disables the user from clicking anywhere in the presentation. I've found that it's typically the slide before the one displaying in the preview or published file that is causing the error. As a side note, I've sent the file to a co-worker who is using the same version of Articulate and she has no problem with the file. Help please!!
