Ok,
Village idiot again.
I was mucking about with the quick filter.
How do I clear it? As it is forced selection from the drop-down menu, there is no "blank" entry to clear the field.
And WHY or WHY is it that the first drop down can' t be extended to show ALL the lists instead of being two rows too short?
Appologies/correction... ONE row too short to not show the whole list.
