I've been using my trial of Photoshop CS6 Extended for 10 days now. I have run into a peculiar problem - when saving a file Photoshop does not display any sort of icon. No thumbnail, no generic, nothing. It's not a huge problem, I can always open the image but not by double-clicking on the icon: it's just not there.
I'm wondering if anyone else has had this problem and if there is a resolution to it - or is it just a bug? I didn't have this problem with the beta version and I've repaired all permissions on my hard drive to see if that was the problem.
The thumbnails in the open dialog are provided by the OS (as is most of the open/save dialog). So there is still a problem with the OS creating or displaying thumbnails.
It's not a matter of blaming Apple without reason, just that Apple has an awful lot of bugs in the OS that don't get fixed very quickly.
Here we know that the OS is responsible for the thumbnails, that clearing the OS cache of thumbnail and metadata fixes it for some people, and that even after that the OS can't always draw the thumbnails when it is supposed to. I have no idea why that would be worse in some applications than others - but the OS is clearly failing to draw thumbnails, and that's not something that Photoshop has any control over.
I have been using Photoshop since version 2.0 and I never had this problem. It suddenly started happening two days ago. No change in my OS, with Photoshop, or with anything else on my machine. Still running CS6 and 10.8.5. When I use Get Info, there is no field for the thumbnail.
