Hi Been pulling my hair out over this.
On Mac OS X while running my app from the command line the window minimize and click to maximize worked fine. When I packaged it up using py2applet it stopped maximizing when the icon was clicked. Solution: In the setup.py generated by py2app change the argv_emulation = true to false run the setup as normal and the window will behave normally thanks to; http://mail.python.org/pipermail/pythonmac-sig/2007-May/018917.html Regards Sean
