MN3 3.7.14 freezes when opening study that has epub included in it.
I’ve tested:
Creating new studies, no issues
Opening studies with no documents, no issues
Opening studies with pdf, no issues
Opening studies with epub, freezes
Creating new studies then adding epub, freezes
Last night, I exported a study (with no documents) that has child mindmaps and it started crashing. I don’t know whether this is relevant.
I’ve tried your steps and others related to ePubs and studies and have yet to see 3.7.14 crash. I’m running a number of other tools as well including Hook, Alfred, Keyboard Maestro, DevonThink and lots more. I wonder if this is something particular to your system.
Sorry I’m no help here but perhaps knowing that it might be unique to your system could help with troubleshooting.
That you for responding Kel. My MN3 is still crashing on me. The only apps running on my mac is Discord, MN3, Chrome and Omnifocus 3. I don’t use any extensions as well.
You don't need to delete the current epub file, just to convert the epub file into a PDF file, then to import it into MartinNote3, and to take notes using the converted PDF.
