[kepler-dev] Help with Pop Up Box in Kepler

Wed Apr 1 17:51:15 PDT 2009

If Derik's assumption is correct, then the two modules are the issue,
and switching from one to another causes the other to no longer be
built. Using a single module is the simplest solution.  However,  if
you do have a concrete reason for keeping the actors in separate
modules, you could create a third suite that depends upon the first
two, and then you would be able to build both modules at the same
time.  Wouldn't this work?
