Oops! I meant Q4_2009.
I was working on a Windows system with Python 2.6. I did not build PIL from
source - I simply downloaded the Windows installer. Reverting to the 1.1.6
version was the only change I made that fixed the font error.
I have another LINUX system that has the same font error that I want to
check. I don't remember which version of PIL was installed on that one, but
I'm reasonably sure it was 1.1.7. Once I test that one, I'll let you know
if I get a similar result. I'll also capture the complete error message on
the Windows system and send that to you.
I hope your vacation was good.
