Ok. I got rid of all the warning (v10617) with mingw32 on Windows (Qt4.5.3). Hopefully this doesn't cause other problems. It is actually quite easy to install Qt (and PyQt) on Windows and our pyqt bindings even compiled without needing any modification. Unfortunately I have yet to figure out how to get anything Python (v2.6) related to work. -Hazen ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
