TB seems to be working pretty well for me these days but there is at least one really annoying bug. I don't have to do anything, just randomly a dialog will pop up saying, "You have chosen to open:" and a file name with random characters ending with @supernews.com. My news server is eternal-september. But it also says, "from: news:eternal-september.org:119".
I assume this is a single post? Why does it think I want to open it? I'm not even using TB when this happens sometimes. It is running in the background. Strange...
