Hi! Sorry, the rotation of pieces is fine. You can rotate the pieces in two ways, always with the right button. At levels 1 and 2, the rotation angle is fixed, simply by clicking the right mouse button on the piece. At levels 3 and 4, first click the right button on the piece and then slide the mouse: the piece will turn smoothly and quickly. For a finer twist, first click the Ctrl key and then right mouse button.
Please see the following video http://www.youtube.com/results?search_query=glpeces&aq=f. If in your system, the program does not behave like in the video, can you send me a video of your screen to see what happens? Thanks! I.
