How stable is the freetype module ? I have been running into problems with it hanging my app completly. The following code should demonstrate the problem. Pressing ESC and you'll see that it has crashed. However if you set the underline parameter to 'False' things work nicely. I am running it on Windows 7.
Example code attached—requires the Times New Roman font to be installed.
