We're wondering if any intrepid users have tried Moviestorm on Windows 7. We've recently had some preliminary results back from our hardware testing people, and they reported no problems with it, but they didn't test it by using it in the same way you do. They certainly didn't make movies with it.
We'll be testing Windows 7 as soon as we can - in the meantime, any feedback you have would be useful. If nothing else, it'll tell our QA crew where to start looking.
