There was a similar question asked but it wasn't exactly what I am trying to do.
Here is a link to the question: http://stackoverflow.com/questions/607291/auto-number-column-in-sharepoint-list-with-link-to-item/799866#799866
Two solutons were offered to that question.
Could either of these solutions work for an imported list I have where Sharepoint has decided which column links to the item with edit menu? I want to change which column does this as I need to change the format and this means removing the column that has defaulted to being the link to item with edit menu.
