I'd say that's informative.  Wouldn't you?

You might contact Steve to see if you can get that version of heatbugs
that does work for him. Or ask him if it is posted somewhere.

I just do Objective-C and only in Unix/Linux. I don't want you to think
I'm ignoring you, it is just that I don't do Windoze at all, and not
much Java. I have been making sure that the Swarm Objective C programs
work, but I don't know that anybody is supervising Java.

The key is to find out if Swarm libraries work at all.  Then worry about
whether the Java Native Interface "overlay" works.

Perhaps you could try the Obj-C versions to see if they work in W-7.
I'm guessing this is the most recent version I built :)

I do recall there was a testing version of the Java Heatbugs that might
be worth trying. You don't mention what version you had.
