SQLNavigator : Toolbars have disappeared

Today, I had to query my Database, start SQL Navigator instance and .... Surprise!!
All my toolbars have disappeared. Happily, I've only to delete one registry folder to solve my problem.
If this happen, all you have to do is :

1. Close all your sql navigator running instances;
2. Open registry; (Click run and type regedit)
3. Go to : HKEY_CURRENT_USER\Software\Quest Software\SQL Navigator
4. Delete Main_Form folder

And you are ready to go.
