Need help in solving Datagrid Problem

Hi All,
I’m using datagrid in a pop-up to display some details.
I have made vScrollPolicy to “auto”.Now it is displaying vertical scoll bar whenever needed.
But the problem is when I tried to use mouse wheel to scroll the details, it is not at all responding(scrolling). It’s working only when I click the arrow buttons in the scroll bar.
The thing what I observed here is, it’s all working fine in the main time line. It is scrolling the entries when we use the mouse wheel in the main time line,but not in a pop-up.
I have uploaded the sample swf. In the sample swf, I tried to demo that.Try to use the mouse wheel to scroll the entries of data grid in main time line as well as in the pop-up(“Click here” button will pop-up a window). Anyone please help me to solve this issue.

Thanks in advance…
