Hi,
Sometimes when I jump, the marine does not stop jumping; I must hit the jump key (KP_0) again (sometimes more than once).
I run the linux version 1.22 (dec, 12 1999) under Debian Sarge (libstdc++-libc6.1-1.so.2 points to /usr/lib/libstdc++-libc6.2-2.so.3).
Sometimes the marine's sight is horizontally erratic.
