Re: "UpdateColors failed" message when in 256-color mode

[Ken Rastatter <krastatter sensotec com>]

In case anybody has this problem running GTK+ 2.2.1 apps in 256-color mode, 
here is a solution:  Try setting GTK+ 2.2.1's new GDK_WIN32_MAX_COLORS 
environment variable to the number of colors you want GTK+ to use.  This number 
must be less than the number of colors that are available on your display.  

For example, on a 256-color display try GDK_WIN32_MAX_COLORS=16 or 
GDK_WIN32_MAX_COLORS=32.
