Hi, I have this problem, that only appears when I use Google Chrome, not with Opera or FireFox as far as I could see:
If I select "Go back one hour" (or any other time), and then click on the button to get new messages, I first see an empty page, as expected. But after a few seconds, the page reloads, and shows me thousands of "new" messages!
