Is anyone else having problems with I&J's on 2.56?  I reverted install back to 2.02 and all works fine?  The problem is it will not display tool path.  It will not even display the toolpath for a part I have been milling for some time?  Weird... something about arc beginning and end.  Great package though... (Mach 3, NF, LC).
I will keep an eye out for the next update...
Thanks,
Robert
