keeing focus between data item and explorer

[dspady]

When I am in the data item window and move my mouse over to the data explorer window, and click it, the data explorer item closest to the mouse becomes active. This is frustrating if I then want to go back to the data item window, I have to find the appropriate item in the data explorer window and click on it. It would be more useful if the focus stayed on the data item topic unless there was a specific click by the mouse right on another item.
