v 5.1.0.47 ZIndexManager bringToFront not working

Hi:

Would like to know if there were any protocol changes from 5.0.0.970 to 5.1.0.47 as the bringToFront method with the ZIndexManager doesn't work anymore.

My init code for the Manager is:

Code:

var zManager = Ext.create('Ext.ZIndexManager');

and I use register to add each of my components.

I call components to the front by

Code:

var check = zManager.bringToFront(component);

Thanks

J.
