When Magical Glass is running you will see a Magical Glass icon in the system tray (located at the end of the task-bar). It is a magnifier that is located above a cursor. Does not hinder work by the mouse, it is good for editing pixels in the graphic editors, and it is simple for examining small-sized details.
What's new in this version:
bugfix for some old videocards.
new stretch filters: "Smoothing" (It require Pixel Shader 2.0 or higher), "A.I." (It require Pixel Shader 3.0 or higher).
