Hi @janosch,
Very strange that you are the first one reporting this problem ...
Seemed that I created a new message in the beforeEmit and I forgot to copy the socketid from the original message, so the dashboard thought that the message had to be sent to all the dashboard sessions. I have solved it via this nice trick from our friend @dceejay.
I have published version 2.0.1 of the node-red-contrib-ui-contextmenu node on NPM. Now the contextmenu is only displayed in the dashboard session where the button is being clicked (based on the socketidof that particular session):
Can you please confirm me if it works!
Bart
