The issue is the cursor motion over the datagrid under the Panel. There is a
trick here that can work.
Put the datagrid into an mx:Canvas, then put a rect stacked over the
DataGrid in depth. Via ActionScript, hack a onMouseDown = function(){} into
the rect by name. When you display your panel, make the rect visible
otherside make it invisible. This will block cursor access to the DataGrid
and stop all the mouse events from firing in the background since the rect
surface intercepts them.
This is clearly a hack, but it will block access to the mouse events driving
the datagrid refresh logic and thus speed up the player when the panel is
displayed.
Let me code this up as an example and post it for review.
Cheers,
Ted ;)
