Hi,<BR>
<BR>
Been doing a few excersises from the PyQt4 Rapid Gui Programming with Python and Qt. The Chapter 13 Python Editor crashes after about 15 seconds on Linux and Windows using Python 2.6 and 2.7 does anyone else get this ? <BR>
If I exit the program crashes I get a Segmentation Error in the Geany IDE.<BR>
