Updated Software - Capture Screen Region has stopped working

[AndyWard49]

I've used the Screenshot Extension for capturing regions of the screen for ages. I updated the App recently - July - and now find that it doesn't work.

I can adjust the area to capture but when I click on the Copy button at the top, nothing happens. Previously, after a short pause, the selected region would show up and I'd right-click it to Copy it.

Can you let me know as and when this is fixed, please? Many thanks
