Me too! After installing 3.8.4 Pro I had nothing but problems. My internet would lock up almost every time I started LW. I would have to hard reset my DSL modem. Disconnect Power. Then I was ok. I noticed that LW was changing my IP address. When I forced my IP to what my DSL modem was looking for then LW worked fine. But, I don't have the DSN setting for my ISP so I couldn't hit the net with IE.
After upgrading to 3.8.5 Pro today, things seem better. We'll see.
Still love the product but the bugs are annoying.
