That's a good call, Andavari, as I type this, the browser sessions seem to be working ok. I have a Windows 8 OS, which may play a role? But, yeah, after about 30 minutes after start-up it seems to be a fairly normal browsing experience.
In my case, after restart, my browser session is still grinding. For example, if I have two browser tabs open and I click on the inactive one to make it active, nothing happens...just freezes. Maybe two minutes later the tab becomes active.
