If I change the SelectChange to return '1', I still get two events in for 'data space' plus one more for the 'plot.' But the plot is easy to id and ignore. But I see what your saying, about the call from idlitmanipselectbox__define.pro when return is '0'. When return is '1' there is second call from graphicsmanip__define.pro instead.
Anyway, it seems either way there are at least two calls to selectChange. The only way I can differentiate is using scope_traceback() and just look for the calls from _idlitmanipulator__define.pro and only consider those valid.
