I can confirm that changing margins works on 5.9.x on KOA2. The hangup for me was repacking the jar on a Mac. I could not find a utility where you could browse and change the contents of a jar in place like on windows.
My solution: If you have Java installed, then on the command line (terminal) you can run the following to update the contents of a .jar:
Code:
jar uf <.jarfile> <path to updated .class file>

Glad to be done banging my head against a wall trying to figure out what wasn't working. Hope this helps someone else.
