[Magic-dev] problems with Magic Tutorial #8: ext2sim, extresis

[R. Timothy Edwards]

Dear I-Lun,

This appears to be a subtle bug in magic version 7.3---the "load" command
does not transfer the box to the new layout, so until you click on the
window somewhere, magic references a lot of commands to the cell that
previously contained the box (which in this case is cell "(UNNAMED)").
I will fix this in the distribution.

Just a single mouse click will fix the problem, as it transfers the box to
the new layout.

This is a magic-7.3 behavior that has not been corrected in the tutorial.
Magic-7.3 does *not* create the extra files (.nodes, etc.) by default,
so prior to doing "ext2sim", you need to do the following two commands:

   ext2sim alias on
   ext2sim labels on

I apologize for not getting around to updating the tutorials.
