The plot background colors look strange, why?

The gradient colors used as background in WinMLS may look strange. This is because your PC supports only 16 colors. It can easily be fixed by selecting more than 16 colors. From the Start button select Settings, then Control Panel. Select Display, in the Display dialog box select the Settings tab. Select at least 256 colors. Another way of solving this is to use the post-processing setup called “NoBackgroundColors” or “BlackNWhite”. This can be done e.g. in Save/Load Post-proc Setup... on the Plot menu.
