http://www.youtube.com/watch?v=n_1R2SxQI_U Having a problem browsing to certain folders (Macbook Pro, OSX 10.4.10) as seen in the video (sorry, capture framerate was slow so playback is fast). Here's the action I'm taking since you can't see my cursor: Doubleclick ghost (HD) Left click School folder Left click 2nd year folder Left click scientific folder Left click entymology folder At that point, the Finder window as well as my HD disappear for about half a second. And then just my HD reappears. I've restarted, repaired permissions. Folder depth isn't the issue because I successfully navigated to much deeper folders. Tried the same thing on my external backup, same folder crashes Finder the same way.
