Now when I waitlist for things if I move to another category or the things I am on waitlist for scroll out of the frame, when I go back to look at it it's no longer highlighted and I have to waitlist again.

Also, often the waitlist button does not work. This has been an issue way before the recent update.

Thanks. We will look into this :).

the hilight gets lost??  ok... i'll check into that

as for the wait list button, keep in mind, the wait list request is going over battle.net.  if battle.net is having issues, the message may not get delivered. 

additionally, the premade leader could log out without disbanding the group.  when that happens, you may see that premade for 3-5 minutes before it disappears.  during that time, clicking the waitlist button will do nothing.

Yup, the highlight is lost and im no longer waitlisted. However, as long as I don't scroll it out of the frame I can still exit out of oqueue and open it up again and it will still be there. Thanks for looking into it!
