Certainly, I can set breakpoints in certain functions which can only be reached by "child" threads, and have no problems with Ups not reaching them. Perhaps that would be a sufficient "fix" for Ups for Linux -- i.e. either have it ignore signal 32 or at least have the capability of setting the action on such a signal? Thanks. Bob
