Apropos to this post (http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=6&MessageID=819312), I attempted to install Vegas MS HD 11.0 (build 75) onto my Win 7 machine. It installs correctly, but when I attempt to drag a .mov vid from the Media folder to the timeline, it will not budge. The .mov file is a lower third that I have been using successfully for months on my xp machine. Why won't is work in Win 7? How do I get it to work in Win 7?
