I'm having major problems in rc515 on Windows.
When I leave the browser open with HG and my computer goes to sleep, then when I come back it won't resume updating the page automatically. I then try to refresh the browser and it goes totally unresponsive. I restart the browser and after some time it again loads the dashboard.
Same thing both on Chrome and FF, and I think not only after sleep, overall slow to initially browse to and F5-refresh.
