I had just finished some nice networklink animations, packed in kmz, downloadable and workable off-line.
The new version results in a error:

Quote:

---

Fetch of NetworkLink "Walk!" failed (/kmz/walk.kmz/walk1.kml):
Security Violation! Url /kmz/walk.kmz/walk1.kml cannot modify /kmz/walk.kmz/walk.kml

---

As you can see the both have the same path.

examples:
- walk in the park
- Soyuz launch

I hope it's just temporarely, for animations done with (locally stored) networklinks are very powerfull.
