[R-SIG-Mac] Bold titles in plots

[thatsanicehatyouhave at mac.com]

Hello,

When I upgraded to Leopard, the titles of plots I generate in R are no  
longer in bold face. This has happened on several computers where I  
use R.

Is anyone else having this problem? I know it's not a big deal (and I  
know RQuartz is being updated), but I have a lot of inconsistency  
between the plots I created before and those I create now.

I'm currently using:
R version 2.6.1 (2007-11-26)
R GUI 1.23-devel (4903) (4903)

Cheers,

Demitri
