Not to pile on, but. As someone who's lost many hours to AP v2 crashes, in front of a client, all I can add is, I feel your pain and you're not alone.
I didn't post then, bc of deadlines. I can add a bit now, but not as much as may be needed.
AP crashes for me in more than one file.
When it did, 'what i was doing', does not appear to have a common cause. The crash behavior was initially, the app hung for about 30 seconds first. Afterward, crashes were ~5 seconds on open. Performing a quick save as sometimes gave me a usable again file, not always.
In one case, I did check into the resource manager and replaced quite a few embedded files. Work seemed to be normal.
Another time, there were no embedded files but the file still crashed.
Another time, i read the log and thought maybe a Calibri file was erroring. The file wouldn't even export to PDF. I thought it was a Word imported style sheet, which I rebuilt the 11 styles from scratch, in a clean file. It crashed. No idea why.
From some forums, the idea seems to be user error. That may be. For me, I can say, AP 1.x did not crash nearly as often. Not nearly.
I know Serif is a smaller developer. Limited resources, I get that. But, instead of sending me the 50% off marketing promotion today, I would like instead for all of the 3 titles to allow me to mark 'F4' as a Layers... shortcut key, an omission that has been know more than long enough to either fix or make comment. Additionally, I would like AP to again be a tool in which I am not afraid to place client work. And as a tiny aside, when I don't update to from 2.03 to version 2.04, don't do it for me.
Downvote, boo the post. Everything I say here, I've read on other posts. I don't care. There was a big rush to buy v2 before the discount expired, which I did. I supported Serif. Today, when I received the 50% marketing email, but still don't have a reliable piece of software, I feel more than a little burned in the transaction.
