cornerstone log 点击down之后无法查看log解决方法

I was having the same problem and emailed Zennaware's Cornerstone support. They sent me these instructions that seem to have fixed the problem for me:

　　Quit Cornerstone
　　Open Terminal
　　Copy paste the following line into Terminal:
　　defaults delete com.zennaware.Cornerstone HistoryCacheUsage

　　Press return
　　Open Finder
　　Select Go->Go To Folder…
　　Enter:
　　~/Library/Caches/Cornerstone

　　and click “Go”
　　8. Move the selected directory (“Cornerstone”) to the Trash.
　　9. Restart Cornerstone

　　The next time Cornerstone prompts you to cache the repository log, choose “Never”.
