Should fix the "black-text on black-background" tooltip problem (although I've always been unable to reproduce this problem....)
Dragging a document without any creator type and any file type (like a document coming from a Mac OS X volume for instance) onto an application in A-Dock would fail to open it. Fixed
Updated the built-in QuickTime skin
Installation of new skins is now even simpler : just double-click on the skin file. A-Dock will copy the skin file in its skins folder, and select this new skin. After that, the skin (like any other skin in the skins folder) can be accessed by A-Dock's main contextual menu
