The dtstyle utility (/usr/dt/bin/dtstyle) is used to change window
manager parameters such as Colors, Fonts, Keyboard attribs, etc. It's
also used to change the background (or wallpaper). Until recently, this
worked just fine on my SPARC Solaris 2.5.1 machine. Now when I run
dtstyle and select the background option, it core dumps. Other
functions, such as changing colors, work fine.
Any ideas? Where should I start looking?
