PS. Note that even the ml2008.1.33e package had some issues for Windows 7 users. These issues were occasional freezing (usually during larger experiments where memory leaks could grow) and in some cases where videos were interrupted. If you are a MediaLab v2008 user and a Windows 7 user and think this may apply to you, these issues have been resolved in MediaLab v2010 (specifically, in v2010.2.19)
