Bejeweled SNAFU?

Got this screen in Bejeweled this evening & took a screenshot so I could check around.  I cannot find a single place to make a  valid move.

In case you’re not familiar with Bejeweled, what you’re looking for is two jewels of the same colour and a third jewel that can be moved next to the first two to create a contiguous row (or column) of three or more identical jewels.

I clicked the Hint button but although it made the “tingle” hint noise, it did not reveal a move as happens nearly 100% of the time.  This has only happened to me once before, over a year ago.  So long ago I was beginning to think I’d made it up.

Can anyone spot a valid move?  Click on the screenshot to biggify it slightly.  Maybe I’m missing something very obvious…
