Many thanks, Wirefreeze, it's now fixed thanks to your guidance. 
Just for the record, this is what I did to reset the LL menu layout after opening the whisker menu:
1) click Behaviour tab
Under Menu, click the following two boxes...
2) position search entry next o panel button
3) position categories next to panel button
Under Recently used, click the following box...
4) display by default.
I've now marked this post as solved.
Cheers
Mike
