Removal of "Open with WebBRowser"

Hello i would like to know how can i disable the "Open With Web BRowser"  function in 5.0.1 ? 
I would like to not have it show in the "Right Click Menu"  or at least not for some users ... 

Thank you ... 

Yes, this is possible.

Edit FileVista\Default.aspx and after this line

        <GleamTech:FileManager ID="fileManager" runat="server" />

add these lines

        <script type="text/javascript">
            fileManager.ContextMenus.FileGridRow.menuItems["OpenWith"].Hide();
        </script>

Save the file, refresh your browser and "Open With" menu will disappear.
