I've just read a post which advised that different users can have different items in their category listing.  I presume that anything that is entered into the 'Tools', 'Manage List type' is visible for everyone ?

My problem is that when we first started using tasks, I entered data into the Category box in Quick Add. However, anything I entered in there, disappeared the first time the item was viewed as a full Edit.  I subsequently realised that I needed to create a Category List through Tools, Manage List Types.  However, in the Quick Add view of the drop down Category list, there are two line items (the first two) which were entries I put in originally.  How can I get rid of them in this view please ? 

Hello Lynn,

The categories you manually type in from the Task Quick Add bar are specific to each user, as opposed to the "Manage List Type" categories.

To remove these, go to "Tools>User Options" and under the 'Category Type' tab you can Add/Remove those user-specific categories.

Let me know if you have any further questions.

Thanks Tom.  That's great.
