I missed two opportunities today because of chat bubbles getting in the way. I wanted to accept a race challenge but before I could accept a chat bubble popped up over the acceptance button and I could not accept. Someone else got to do the race. I believe this same thing happened to me twice today. I was also unable to thank someone for a gift because a chat bubble popped up in the way and by the time it disappeared my friend was gone too. Next time I will IM her but there is no other way to accept a challenge. I don't have those races in my Quest Log so I can only do them if someone challenges me. Rats!
