Antialiasing for text display

On my computer the display quality of text is quite poor. It seems that the Text (e.g. an Arial multi-line text) is drawn without antialiasing, all pixels are either white or black. AutoCAD LT running on the same computer produces soft edges by using grey shades and has a much better text quality. This is especially annoying when text is copied via the clipboard to be inserted in a bitmap, the result is terrible. When text is printed, the quality is fine.Is there an option to improve the display quality of text?Andreas
