Right click doesnt work, i can't see menu to whisper, report, ignore etc.

this happens for whisper and invite. i started by whispering someone and it whispered the wrong person. and i tried to invite the person i wanted to talk to into my group and it invited the wrong person. and then i tried to click on the person i wanted to speak to but using his name in another line and this time i couldn't even get the right click whisper invite ignore menu to even come out. as in i right click his name and no menu. and then finally i tried a 3rd line with his name to whisper him and this time it whispered the wrong person again but it was a 2nd completely different wrong person.

Annoing problem, its happening every whisper, please fix this.
