MySQL Editor Hangs on attempt to Launch I have just downloaded the latest Community Installer (5.5.27) along with the MySQL WorkBench (5.2.41). I clicked OK on all default settings on setup.

When I try to "Open a connection to start querying" on the WorkBench home page and chose "Local Instance MySql 55", I keep getting stuck on a never-ending "Opening SQL Editor" screen ("An SQL Editor instance for "Local Instance MySql 55" is opening and should be available in a moment")

Any idea on what could be wrong ?

EDIT : 
I am able to access it from command line and query it successfully. But still not from query editor.
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:


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