Sorry, METIS doesn't crash on Unix but gives poor quality

An update on my previous post, sorry... it works with the UNIX version (source-compiled) but not with the Windows version.

However, it gives very poor quality partitions... Here's the output of a 28-way cut:

There are only 12 non-empty partitions out of 28... why would this be the case? Can I not restrict it to have 28 non-empty partitions?
