Beta3: setModal() on Window still allows tabing through components under it.
The problem can be seen in this( http://www.sencha.com/examples-dev/#...ace:helloworld ) sample, and I can reproduce it in my code.
When you go to the example above,click on "hello world" button and then, using your keyboard, you can navigate through other samples without problems - with so-called "modal" window, on top.
Thanks for pointing this out. I've filed an ticket against the team and will update here with any progress.
