Pasting in null into text field, pasts the characters: and not null itself

Hi there

Has anyone else come across the following behaviour in ArcMap?

When I am editing an attribute table in a Feature class, sometimes I need to replace a single value in a field with null. I will often do this by simply coping one of the other fileds ear by which has a null value in it.

However I am finding that sometimes if I am pasting to a field which a a data type of text, it ends up storing the characters: <Null> rather than null itself.

As ArcMap displays Null values as <Null>, it is impossible for me to know when this is happening. I then find I have to locate them using a select by attribute query and use the field calculator to replace them with null.

Now I could use the field calculator all the time but using it for one value takes longer than it goes to simply copy and paste a near by null.

I am using 10.1.1 but I find the problem occurs with any version of ArcMap I use from at least 9.3.1 onwards.

Kind regards
