SYMPTOMS
If you run MS-DOS Shell on a system using a CGA monitor, some colors may blink.



RESOLUTION
Possible solutions to this situation are to re-expand the video files, remove the &quot;bright&quot; color selections if they are unsupported, and to refresh the screen within Shell. These options are described below:


 * Expand the CGA files for MS-DOS Shell to the MS-DOS directory. In some cases, Setup detects a different graphics card and expands the wrong graphics support with MS-DOS Shell. Check to see what kind of monitor is present, then expand the appropriate files. The proper files for each type of monitor are listed in the MS-DOS 5.0 &quot;Microsoft MS-DOS Getting Started&quot; manual.
 * Some CGA cards don't support the bright colors. Any color scheme listed in the DOSSHELL.INI file that has a bright prefix blinks if bright colors are not supported by the CGA card. To prevent these colors from blinking, use a color scheme that does not include bright colors, or edit the color schemes in the DOSSHELL.INI file to remove the bright prefix on the colors.
 * If you have a screen saver loaded and task swapping is enabled, when you swap applications, the colors may blink. Press SHIFT+F5 to refresh the screen and eliminate the blinking.
