Prevent Unity from blocking task bar?

Whenever the Unity editor window is active, the task bar (set to auto hide) won’t pop up when I move the cursor towards the bottom of the screen. The only way to switch out of Unity is via alt+tab or to minimize.

I’m running Unity 4.2.0f4 on Windows 8 64-bit.

It’s probably a bug, but does anyone know of a solution?

Fixed on 4.3!
