This seems to happen sometimes on windows laptops. We haven't quite narrowed it down, but it appears to be memory related in some way... it also seems more prevalent in Windows 8. We are looking into the issue and hope we can get it resolved, but it will probably mean a pretty major overhaul of how data is structured to prevent memory issues. Another partial fix we will be implementing soon is to save your settings so that if it does crash you can start over from your previous location without loosing anything.
Did this help? Tips are appreciated...
