I am using version 2.0.5.0.9 in a Windows 7 ultimate machine, and I am glad to report that it runs rock solid, with no issues whatsoever. I know the last post here is three years old; but, for someone that wants to use something similar to the OSX dock this is the best solution around, it even has the reserve windows option that runs very well, congratulations on the great programming job you did, thank you very much for sharing your work.
