This is definitely a strange behavior. I have never observed any issue with right mouse clik. Would you mind telling us if you have noticed any specific action is stopping this function? What is the OS and XD version of your machine? Is it happening with a specific file or all the files?
Sorry for the frustration. I understand this could be annoying. Could you please share a short video of the issue because we are unable to reproduce the issue at our end? Does that happen randomly or have you noticed any specific action triggering the issue?
