Strange behavior....
I have a MS12 project that opens up fine in MS12, but hangs in MS13.
Another few MS12 project that opens up in MS13, but first yields the message, "The file appears to have been created in an older version of Movie Studio Platinum. All tracks may not be displayed properly. It is recommended to create a new project."
There are 2 video tracks and 3 audio tracks for that project (and it did load correctly!). But is anyone else seeing this type of behaviour with older projects?
