Hi,

 

I'm unable to remove a mention once it's added in the message.

Even worse, once added I can't type anything after it !

example:

You can remove it.

I've just edited the topic with your permissions and clicked just after the mention, then hit BACK twice on the keyboard and you'll remove the mention.

Sometimes it works, sometimes not.

Which browser do you use ?

I use Firefox, next time I will try an other, but it's cumbersome to login on an other browser just to post or edit a message...

EDIT: ok it's Firefox, tried with Waterfox, it works.

Yeah, could be the browser. I am using Chrome.
