Bug? Diff. between privilege clicks...

When I click privileges tab, and I want to add a user there are differents I saw:

a.) I click to privilege first (ALL), to user next

b.) I click to user first, and privilege next

One of cases it is make possibility to check grant, another is not.

That is based where I click first...

Bug?
