I wasn't. I'll try it now. Thanks for the tip!
EDIT: Agreed, when right-clicking I got to the dialogue boxes perfectly. I ran into two problems though...
1) Occasionally, the "Goodbye" button is missing from the chat box, meaning I have no way to stop talking to the NPC except pressing the Escape button. Since there is the Escape button, this problem is avoidable.
2) This one was a little weirder. :blink: I'll explain everything I did, 'cause I don't why this happened.
The first time I ever logged on as Ducky, I tried to talk to who I now know to be Mr. Clubtail. After failing, I quit.
This time, to be safe, I logged in as Cera and headed straight for Mr. Threehorn. I didn't even notice whether Mr. Clubtail was in his spot or not. I chatted, it wokred fine, I went back to the main menu.
I logged back in as Ducky. I decided to talk to every NPC to see who everyone was. In order, I met Buzz Conedrin, Mama Flyer, Mama Swimmer, Grandpa Longneck, and skipped Mr. Threehorn. But I was sure there was one more. Hadn't there been a cube straight ahead of the hill where you begin the game?
I checked the map, and found it indeed said there was somebody there. I moved until I overlapped with the green dot on the map. Mr. Clubtail had disappeared!
I logged out and then logged in as Spike. Mr. Clubtail was back. I never knew why he was missing that one time.
