Jimmy,

I see that "2000" is hardcoded into snswnd.f for the maximum number
of levels, so I'm assuming this has to be increased to 5000.

If you still see crashes, then compile the code with "-g" turned on
in the FFLAGS in the Makeinc.xxx file, and then use "where"
in the debugger with the program executable and core file to track
down the point where the program is walking off into space.
