Procedure position in Editor after clicking on name in Navigation pane

I recently upgraded to Toad v11.6.1.6 and in the Editor tab when I click on the name of a subprogram in the Navigator pane, on the right side the cursor moves to the declaration of that procedure and it appears in the center of the Editor page.
In earlier versions clicking on the sub program used to move to the procedure and it appeared on the top of the Editor page.
Is there a setting that will change this back to the normal where the selected sub procedure starts on the top of the page instead of the center? Please let me know if you know a way around it.
I have attached an image showing how clicking on sub program r050_build_summ_rpt_prc displays the program in the center of the editor page instead of the top.
