Gus - I am sorry to say that I have installed the new version, relauched finder, did the force quit on the the com.apple.quicklook.ThumbnailsAgent app and nothing has changed.
I’ll be out of town for the next few days and working on my laptop, I’ll check to see if I have the same problem there and will let you know.
The new build [7.4.6b1 (16645)] fixed the problem for me.
After that, I’m getting previews of Acorn files again.
I’m glad it’s working for more folks now!
I’ve got yet another new build up to try it when folks get a chance: https://flyingmeat.com/download/latest/
I tweaked a couple more things which I think might make thumbnails and previews show up faster.
Also, if you’re having problems with it not showing up, do you by any chance have multiple copies of Acorn installed?
There’s a new build up again, for those who’d like to try it. I had to tweak some things for submission to the App Store, and there shouldn’t be any changes - but sometimes things go wonky anyway.
Missed all the replies here somehow - just a quick not to confirm that the released 7.4.6 fixed things for me as well. Thanks for the quick turn around!
