Need to restart XnView MP after updating DNG preview

[FKCapitalism2]

1. Open DNG image in full screen
2. Then open with Photoshop using Open With menu and edit then save and close
provided embed full size preview enabled in Adobe Camera Raw it will update embedded preview inside DNG file
3. Go back to to thumbnail view
4. Open DNG full screen again

Preview image is not being updated.

Preview only updates once close XnView MP and open again.

I understand XnView MP caching files in memory, is there way to make cache check timestamp of files on HDD, if timestamp on HDD newer than one in cache then then force re-load that file?
