Live Book Issue

I upgraded to “Backtest” a couple of months ago and have been playing with the “live book” feature for 3 books. They have been working fine until a week ago. Now, one won’t create a PDF of the book. When I try, it just bogs down my computer and I have to kill firefox. The other two have no issues with creating a PDF. And, the other screens on this one (statistics, transactions, etc.) work fine. Does anyone know what might be the issue. The book is:

We found and fixed an issue affecting the PDF generation in certain edge cases. Please let us know if you're still having issues with it.

Thanks.
