When in a group chat window, if you click the show button, and look at the list of members in the group, you are not able to right click a member and perform the same actions that you can when in the main chat window . Right or left clicking clicking the member does nothing.
Find some one in the main nearby people listbox in the main chat window. Right click their name. You should see profile, pay, IM, etc. Now go into a group chat window. Click the show button, and find a persons name in the listbox that comes up. If you right or left click on a members name you can not get a menu to come up like you could with the main chat windows list of people.
