Datagridview scrolling problem

Question

Hi guys, I have a datagridview which only holds 8 rows and then the user has to scroll down. I only enable the Vertical scroll bar. However as soon as the 9th row is added, which should cause the vertical bar to appear the whole application just freezes and stays in "Not Responding" state. Then I have to kill it through the Task Manager. Also if I disable the scroll bars the application works fine but I must use the keyboard to navigate in the Datagridview. I have searched various search engines for an answer to this but have found almost nothing. Thank you for your time, Andreas
