On my playbook, when I receive an email it shows up in yellow which means it is unread. I click my finger on it, then click off, which should turn it to "read" but sometimes it takes over 3 minutes and a bunch of clicking to do this, even if I use the "mark as read" button. Same with deleting. I have to keep pressing delete over and over for minutes to make the email delete. I have a strong wifi connection when I do it so that's not the problem.
Any ideas why this happens and if anyone else is experiencing this?
Thanks
