When I get time I will try to build ABCL from source using the instructions
on the web site.  From what I read, all I need to install is SDK and Ant.

Also, note that in the original email I wrote that I had an error on Linux
as well with Run Program.

For now, run-program bug is not a show-stopper for me on Windows.  Instead
it is the stack overflows when loading libraries from Slime (which I posted
on the Slime group).  In the meantime, I will do software development on
ABCL on Linux.
