Accent menu no longer appearing


I was wondering if anyone else was having this problem?

When I normally hold a key down for a little while, a menu pops up with a number of accents to choose from:


This no longer appears for me in Scrivener.
It works fine in Scapple though.

Any thoughts would be much appreciated as I use the accents quite regularly in one of my fiction series.

Many thanks,

I am working on Scrivener vsn 3.2.3 and MacOS Big Sur 11.7.2

Rebooting is the first thing to try.

Ah, thanks for the reminder!
I could have sworn I had rebooted previously, but I gave it a go anyway and it worked.
Many thanks!
