Spent about 3 months tweaking this installation of directory opus after a clean reset of windows 10 and now I find I cannot have live folder thumbnails because every time I turn them on they will eventually gain a black background.
The same folder in windows explorer does not show them with black background.
I can easily fix the the problem (for a very short time) if I use Disk clean-up to delete the windows thumbnail cache.
It seems I might have to do a total reset of Directory Opus and start again with the the caveat never to toggle or play with the folder thumbnail options.
Is there some Directory Opus syatem file that I can delete/reset to save doing this that might fix the problem ?
