Tutorial stuck with Mac Yosemite

I’m new to Scrivener and Mac Yosemite operating system on my laptop. I am simply going through the tutorial, checking out the program and clicked on the Spacewalk document in the Research folder while in the tutorial and going through the steps. Now I am completely stuck. Scrivener will not allow me to go back, forward, return to beginning of the tutorial or anything at all. Yeah, really frustrating. I’ve tried force quit, restart of program, restart of computer but it always brings me back to the Spacewalk page with no options. Anyone have suggestions?

Yup, that’s annoying one, unfortunately there isn’t much we can do about it as it is a core OS X bug. Here are the bug details and how to work around it.
