I was able to get the MultiLeader to work by editing the settings in the dialog boxes.
Under Format, Multileader Style.
See the attached screen shots with my settings.
I have a left justified & right justified style depending weather you are pointing right or left.
Let me know if it works for you.
Huh, I didn't think anyone used MLEADER when QLEADER is available. MLEADER seems so cumbersome compared to QLEADER, once I tried it to see what the issue was all about with the justifications. QLEADER has the same settings dialog BTW. I just wonder what settings the others had where they were having a justification problem and had to use a LISP to accomplish a core command?
My bad! This was Qleader.
But I do believe they are similar.
