MySQL Editor Hangs on attempt to Launch

Thanks Mika, I tried your solution in workbench (5.2.41). It worked after I cleared the passwords in the vault (click Manage Connections) and restarted the WorkBench.

To clear passwords stored in the vault, I did the following:

1. Open MySQL WorkBench the you will see the home page
2. Click Manage Connection at bottom left corner.
3. In Manage DB Connections, click Clear button besides Store in Vault...
4. Close it and restart WorkBench.
5. Double click Local instance mysql in home page, now you db will popup.

I don't know what happened. I launched a command window, it worked. Then I retried, after clearing the password vault, and it worked.
