The black version looks great! Still there were a few things I didn't like:
. like someone has already said, it would be nice if there was the little button on eMule, the one that closes the window and adds the icon to the system tray... I hope you know what I mean lol;
. when you click on the start button, it shows the name of the user up there, which is fine but I don't like the font you used ;
. and the pic of the user isn't clicky, if you clicked on that pic it was supposed to open a window with the users accounts settings, etc.. but it doesn't.
