It's weird though, the TrackPoint and External USB Mouse work without any problem. How did you get rid of them, are you having the issues in newer builds by any chance?
There are no .ISO's until (or even if) it hits for the slow ring. This is standard since the start of the program. Edit: You can make your own by converting the ESD file.
I've noticed that at least some system notifications are delayed by about a minute before displaying. Is this a feature or a bug? For some programs, it's highly annoying.
I'd be surprised to see a new build before the beginning of May. The next build we'd likely see is the one presented at the BUILD conference, or a variation thereof. If we do see a build before then, we won't see the BUILD build as quick as we'd like. Why would we like it? Because it's what they are referring to as the first Release Candidate. In reality, it's not really a candidate for release, it just means that any changes thereafter will be just bug fixes in preparation for the RTM release.
