flex grid scrollbar pushing all columns to the left

I have a flex grid where I have the verticalScrollPolicy="auto". But every time when the scrollbar appears all the columns get pushed to the left, making the colu开发者_Python百科mns not align as they should. I tried setting minWidth on all the columns to prevent this, but that doesn't seem to work. Any ideas?

This is the default behavior of flex dataGrids. If it bothers you, you can set verticalScrollPolicy="on" which will draw the scrollbar whether or not it's needed, and the grid will not resize.
