View customization problem can not select the column
at One of our customer we realized that, while we customize views in crm we faced a problem, that we can not select the columns on views. The reason of this problem is internet explorer setting, open internet explorer-->tools-->internt options-->security-->local intranet-->sites--> add--> then wirite "about:blank" and click add. Save and close dialogs. Open crm and you can see your view problem has gone.
