Bug Description

Using Ubuntu 13.04 x64 fresh install on Thinkpad E420s.

If I define a hot corner (such as window spread on top-left and top-right) using either Unity Tweak Tool or CCSM, they work fine while my laptop is not connected to an external monitor. The monitor is set to be to the left of my laptop in the Display settings

When I connect via VGA, the top-left hot corner no longer works (on either display). The top-right one continues to work.

On the other hand, if I move the external monitor to the right side of the laptop, the top-left continues to not work on either display, but the top-right works on the external display. Perhaps this is the intended behavior, but it seems more intuitive if you can use the hot corners on each display.

On gnome-shell, I would intentionally misalign the external monitor and the laptop display so I could use the top-left hot corner on the laptop screen. This is a very useful behavior.

As a workaround, I will just use the top-right corner, but I would prefer if the top-left worked as expected.

I'm seeing the same behaviour on a dual monitor desktop set-up, including the right hot corner working on the second monitor. My screens are 1440x900 (primary - left) and 1280x1024 (secondary - right).
