The vertical scrollbar appears as soon i move my mouth in its area and
it disappears again if I click on a object of the active container

>>In a form a Display a grid inside a container class, when I click over a row of this grid I call a form method in which I remove the container object which contains the grid and add another object with some details.
>>Now it happens that the grid scrollbar belonging to the removed grid is
>>still visible. How can I get rid of it ?

>I have not seen that behavior. Does a simple ThisForm.Refresh() work?
