An Unresponsive Window Freezes the Whole Desktop

---

When debugging UI Applications, this application becomes naturally unresponsive when reaching an execution breakpoint. As a consequence, I see the "Force Quit or Wait" dialog, which freezes the whole desktop.

And this is of course not only the case when debugging, but happens as well for a "normal" application freeze. Sometimes I just notice a desktop freeze and dont know whats going on until I find this "Quit or Wait" dialog.
Please make this window not freeze everything else.
