Hi. I'm having problems with the 'site blocking' feature. I added a bunch of sites I want blocked on my computer, and enabled site blocking, but now lots of other sites are being blocked. For example, Amazon.com - the shopping and kindle ebook website, is blocked by the site blocking. I could turn off site blocking to access the site, then turn it back on again, but it sort of defeats the purpose of having an active site blocker if I have to toggle it on and off to access sites that aren't on my blocking list.
