add /root/my-roxapps (that is where X-ToysGUI is located) to GETTEXTSCRIPTS in /usr/sbin/momanager; it is about line 133,
change it from
GETTEXTSCRIPTS="`find /bin /sbin /usr/bin .....
GETTEXTSCRIPTS="`find /root/my-roxapps /bin /sbin /usr/bin .....
When launching momanager you should find it in the frame "Scripts that do not have a mo file"
do NOT change momanager but copy above script to /root/my-applications/bin and momanager will find it.
