How to turn off Speed Slice in PTX Print?

Question

I'm really enjoying Speed Slice as I adjust Genesis for the umpteenth time. But how do I turn it off and get back to the full print run?

I tried closing PTX Print, using Tidy Up and then close/reopening, starting with GEN 1 (don't get the front matter). I can't find a button or switch or anything.

Answer 1

(Obviously the design of this needs to be re-thought! It isn't obvious at all... My apologies!)

Select SpeedSlice, and then instead of clicking OK, just click Cancel and it will go back to doing the whole book.
