PSE 2026 shows all thumbnails but double-clicking gives grey box with question mark and no full size image
I’m running PSE Organizer v26.0 on a 2025 iMac with OS 26.3.1. I had to upgrade to PSE 2026 because 2022 no longer worked. The catalog is displaying all the thumbnails fine, but whenever I double click on ANY of them (JPEGs, TIFFs and RAW) I just get a grey box with question mark.
If I SLOWLY move the Zoom slider, I can get it to show a full size image, but if I slide too far, it once again gives me a grey box. So I have to move the slider gingerly. Of course, I would prefer to just double click on the thumbnail, which always worked before.
I have deleted the cache. I’ve reset Preferences. The Manage Catalogs function does NOT give me a REPAIR option. Only Optimize, which made no difference.

Any ideas? Thanks.
Duncan
