      Noticed these problems here too. Hopefully some Java guru will have a

  I've noticed it to on fedora core 3.  Using the -Xmx<some large val>m to 
increase the heap size helps out.  I don't know what the default is, but does 
seem to small.  It certainly is a memory leak issue, because I do see errors 
like this from the window I run it from when it starts to misbehave:

      [java] Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: 
Java heap space

  In theory, java is supposed to reclaim memory so there shouldn't be memory 
management issues.  I wonder if some pointer isn't being cleared, and therefor 
memory from the map isn't being freed as it should.

  One can see the problem pretty easily - load one of the world_x_y maps and do 
enter north/east/whatever a few times.

  Increasing the heap size really just masks the problem.  OTOH, I think the 
default is probably pretty low for how much memory most systems probably have 
now days.
