Unity starter not reachable with multiple monitors (to the left)

[Zordid]

Binary package hint: unity

When using a Laptop to the left of a main monitor and when using Twinview with Nvidia or Xinerama - the unity starter is placed "in the middle of the combined desktop area". When having a window fullscreen on the main monitor (or having it reach the starter), it is impossible to get to the starter!

attach screen short than it will be more easy to understand and solve it

Here come two screenshots presenting the situation.

The left monitor is my main monitor, so the Ubuntu starter is shown "in the middle" of the complete desktop area consisting of two screens.
When this starter is hidden, one as to touch the left edge of that monitor's screen area - which is the exact middle of the complete area. Even the mode "touch upper left corner" is tricky - since moving the mouse pointer over the Ubuntu logo in the left corner does not fully display the starter, instead it triggers an animation to slide the starter in. To fully show it you must hit the upper "left pixel" - which is almost as difficult as reaching the "left edge"!
