Alexander Schmolck reported similar problems trying to call pylab from an embedded app. My response to him at the time was: > Eeeeew, that looks really dangerous.

Perhaps he has made some progress since his original attempts and can advise... JDH > My C++ application has an event handler to run a python script when the user > so chooses.
