I was using this beta for some time with great satisfaction,alongside the yahoo beta 9 and IE8,I HAD FEWER PROBLEMS ALSO during this time.Then i made a big mistake by downloading SP3 BETA,i crashed and burned big time,major wipe out,total system re-install with much lost info,my fault,hands up.The indication was failure to recognise driver files.I would welcome the chance to run the 9 beta again as it was a pleasure to work with.
