Gimp Toolbox and Layers, etc. docks obscured by Unity Launcher and Panel

[Mal]

When Gimp is run after a fresh install on 12.04 Precise Pangolin, the Toolbox and the Layers, etc. Docks are located in the top-left and top-right corners of the screens such that they are partially obscured by the Unity Launcher and Top Panel. This results in the Toolbox, in particular, being unusable, because some of the buttons are inaccessible. It is not possible to move the docks away from these positions.

I was able to work around this problem by changing the "Window Management Hints" in "Preferences/Window Management" from "Utility" to "Normal". After closing and reloading the Gimp, this places the docks in normal windows that are clear of the Launcher and Top Panel and able to be relocated. However, this will not be obvious to a new user.

Similarly annoying is getting *all* of Gimp's panels to appear when selecting it as an application. You get to choose just one when keyboarding through open applications. Only way I've solved this is by cycling through all other open applications and minimising them. Unnecessary.
