Bit of dumb one, but for a few weeks now, pressing Z to thank someone hasn’t been working, if I press Z when the prompt comes up I just get the standard chat ring.
It is a bit annoying as it seems good manners to say thanks if someone offers to help, but I don’t have time to be targeted a tank and looking at options.

I have checked all the settings and I don’t see a check box for this specifically.

Any ideas?
