I've noticed that on lists of things such as contacts, companies, and tasks that the column headers disappear as soon as one of the check boxes is checked to select a line. This is annoying because I often have more columns than will fit on the screen and I need to pan across to see more data and lose track of what columns are what. So then I have to uncheck the line (or lines) to go back and see what the columns are.
Please consider leaving the column headers displayed when a line is selected. I realize the action links would have to be moved someplace else such as a new line.
