Strange, with a little more effort I can now reproduce the problem, 
too. Apparently Font Book wasn't installing the latest version over the 
top of the old one correctly. I must remember to remove old fonts 
before I try and install new versions.

So I can revert to the correct behaviour by installing an older version 
of the font with Unique Name: "FontForge 2.0 : Neo Euler : 18-9-2009" 
(quite a lot older, I know).

Does this help track down the problem, Khaled?
