I was attempting to tag an mp3 file I had just reprocessed using Audacity.  This is something I do all the time, usually to amplify the volume of tracks or remove long periods of silence.  When I began, I was notified that v2.2.2 was available.  I took the download, closed Picard, and installed as usual, keeping my settings.  Upon starting v2.2.2, everything seemed normal.  I selected the folder, then highlighted the file.  As I prefer to enter my own tags, I began as usual by selecting albumartist.  At that point, Picard basically froze.  The Win7 "circle" just went around and around.  After a few minutes, I closed Picard using the Task Manager and brought it back up.  I had hoped this was just a normal occurrence of Windows not processing something correctly.  Unfortunately, the same thing happened after I restarted.  I left Picard running for 15 minutes but it would never respond.  Thinking maybe that mp3 was somehow corrupt even though it played perfectly in VLC after I exported my changes in Audacity, I tried another file from another artist that I had also just edited.  Picard v2.2.2 again froze upon selecting albumartist.  Again killing the process, I tried again with a much older mp3 on my hard drive.  Same result.  I then uninstalled v2.2.2 and reinstalled v2.1.  The problem went away and I had no further issues.

This is the first time I have ever had an issue with Picard on any platform (I use it on Linux Mint at home).  I will be glad to provide any other information needed to help diagnose if this is truly a bug with v2.2.2 or just an issue with my PC at work (on which I am not having any other issues).  As this is my first visit to this ticket area, I apologize if I have left out anything normally expected in a report.
