Party/Raid Issues

[Laquin]

I'm noticing that when I have Quest Helper loaded, I am unable to right-click on character portraits inside of an instance to do things like change loot rules or trade. I sometimes hear a noise when I click on it, like it loaded it but nothing shows up. And as soon as I'm out of an instance, I can do it again. Can you let me know if this is an issue with this add-on or Quest Helper? Thanks in advance.
