USM in Photoshop CC not working?

[Sarah_]

Hi Damien,

I'm using your client sharpening action and it won't seem to work on one image in a batch. It has worked fine on all the others.

I have gone back into the history to undo the action and gone into USM to manually input and the same thing happens.
- It flattens
- It zooms into 100%
- It brings up the USM window with the correct numbers in each part, however, no sharpening occurs.

I have tried closing the file and PS and retried and the same thing happens.

Please help!

Ta.

Is this because it has opened in Quick Mask mode?
