Bugs with import from archive in iMovie 11 on Mountain Lion

Click import from camera archive pulls up a finder.

When I click on a folder with sereral archives it just hangs without opening for 10-15 whole minutes.

Sometimes it will finally show the contents of the folder sometimes it will just hang forever and and I need to kill imovie.

After it pulls up the contents it can import 1 archive fine.

Then if I try to import any other archive it says that the folder is not a camera archive.

If I kill imovie and restart I can repeat the sam all over again.
