When I am doing a search on my side for something I am working on. It also applies across to others working in the same list. When the limitation should only apply to me and what I'm working on - not for everybody working in that list.
The attached screen shot is my collegaue trying to figure out where all her tasks are gone and it's only because I'm working on something and saw the 'miss' in the search field that I realised what was happening.
