Bret,

    There are probably better ways to do this that I would think of if I 
weren't so tired, but this one will get you around the JumpError 
problem.

form = callcc do |cc|
   ie.document.forms.each do |form|
     if(form.action == "start")
       cc.call(form)
     end
    end
end

puts form.inspect
"#<WIN32OLE:0x28bcf48"
