ExtJs 4 is not a framework ... is a never-ending battle!

I won a battle:

Code:
Ext.onReady(function() {
...
Ext.application({
... launch: function() {
... Ext.getDoc().on('contextmenu', function(e,t,eOpts) { if (e.preventDefault) { e.preventDefault(); } else { e.returnValue = false; } return false; });
This solution stop right click events on document browser but leave it for ExtJs ones.

I can right-click on TreeMenuItems, panel desktop and so on.

ciao!
