I'm testing Csound/Python on a Mac, using: OSX 10.5 MacPython2.4.4 Csound5.08 OSX binary installer wxPython 2.8 unicode for Python2.4 When running PartikkelExplorer.py (from the terminal), I get $ csound loaded Fatal Python error: PyThreadState_Get: no current thread Csound tidy up: Abort trap Abort trap $ by inserting a print statements before and after the self.csound.compile() statement in cs/csModule.py I can verify that the crash is related to that statement (csound.compile()) What could I do to try to make it work ? I've tested the wxController.py example, and that works (I rewrote the from wxPython.wx import * to import wx and changed subsequent references accordingly to make wxController.py work) best Oeyvind
