I had 2 files open. I wanted to try to check the graphic output. The file that I had been working on, I went to Print Mode, tried printing/exporting a page range. After typing the last page of the page range (from 16 to 1 - I just wanted to export page 1), Dorico crashed.
Here are the files… I zipped each up so they will need to be unzipped.
Dorico Diagnostics.zip (462 KB)
application.1.log.zip (6.1 KB)
Dorico 2_2018-10-08-205831_Robbys-Mac-Pro.crash.zip (22.6 KB)
