Yes, it has been doing it for about a week now. Usually starts about 11:30 and clears up at about 11:35. During that time it just searches and searches and does not allow canceling a reservation or making a reservation. The other thing I have noticed at various times during the day is that the recaptcha thing doesn't work and states that it can't find the recaptcha website (a little grey window opens with a message like that). I usually have to log out and back in to overcome that.
