GoMenuItem and GoLink with target="_Blank" don't work correctly inside a Menu

We have strange behavior with GoMenuItem and GoLink components inside menu items

To reproduce the problem i created the following simple test case:
Created a menu with 2 levels and gomenuItems and MenuLinks that all open 'otn' in new '_blank' window.


The menu is the following:


1. In the menu above if i select goMenuItem 1 then new window opens behind my window (internet explorer 7,) works correctly in mozilla. goMenuItem 2 works correctly in ie7 also.

Funny thing is that if in ie7 you have a second tab opened then it works correctly.

2. goLink 1 works correctly, goLink 2 does nothing.

Is this a bug? any workaround?
