After I correct tags, the final three steps of my workflow are as follows:
Correct subfolders from metadata -> Correct filenames from metadata -> Close files (save changes)
Jaikoz is frequently crashing during “correct filenames from metadata”. I can’t reproduce the problem every single time, but it usually happens when I am working with at least 50+ items. I am on OSX 10.8.5 and using the latest version of Java (although this was happening before I updated Java a couple of days ago). I can save the crash report next time and post that if it helps.
