The freezing issue was sorted in the latest hardware revision.
Mine is a B and thus had the problem, the C revision had a small design change an the firmware update done to it, that was released pretty much around the same time I did the review from memory.
So really depends on what revision you got.
It also didn't happen straight away, after about a month it started, and it would lock up on an almost daily basis if I turned my PC off for the day, firmware upgrade fixed it and added a couple of extra features
I always make sure all my hardware is up-to-date with firmware as much as possible.
