All Thumbnails in Folder Being Recreated, after moving a single file to another location.

[danielk541]

I have folders with multiple PNG files. Thumbnails are created the first time I visit that folder. Then if I move one file out of that folder, I have to wait several minutes while thumbnails are created for all remaining files.
With a folder of 1000+ images to sort this can be pretty tedious.

Long time user, first time i've experienced this. No changes recently made - running 64 bit version 28.00.1200.

Can't reproduce.
