Ideas for improvements and requests for new features in XnView MP
Hey thanks so much, you found the trick ! Actually I had no ticked Use thumbnail cache so the Get Thumbnail Size button was greyed out. I ticked that cache thing, clicked on the aforementioned button and got my thumbs all 160 x 160. Then I unticked the cache option again and now my folder thumbs are back to normal while picture thumbs are still OK as before. Waoh, I wouldn't have thought of that so thank you soooooo much ! I had not changed any options when upgrading though. Hope it helps other people who encounter the same inconvenient I did.
