The 1.0.2 is my current version of pymel. Sorry for the title with 1.0.0 instead. After your question, I tested an older version of pymel: 0.9.3
I got an error saying that MAYA_APP_DIR is not set. Following this, i set MAYA_APP_DIR in system path. And IPymel 0.9.3 works fine. With IPymel 1.0.2 it is also good. Cool, but MAYA_APP_DIR don't set by default ? -- http://groups.google.com/group/python_inside_maya
