Lesstiff that comes with Mandrake 8.1 doesn't work well: - Sometimes variables show incorrect values within DDD. - Sometimes robot' sensors show incorrect values within Saphira (a tool to develop robot controllers). Both applications: - Use motif (or compatible) libraries. - Work well with Mandrake 8.0's lesstif. - Work well with Mandrake 8.1 if I uninstall lesstif and install openmotif (I recompiled DDD but not Saphira).
