When i have four thumbnails in a folder, viewing miniature mode, and then modify the content, the four images won't update to the new selection.
For example, if i have images A, B, C, D, the thumbnails would show them correctly. But if i change the selection to A, B, C, E, i'd still see the old version of the folder preview. Is there any way to purge the old cache? At the moment i would have to delete the folder entirely and start from scratch.
