R help - Aug 2005 - Lattice on Mac OS X & Strip Labels

Hi,

I'm running R 1.9 on a Mac with OS X (v10.3.9).

When I use the lattice package I never see text in the strip labels.  The 
labels appear and I can change their color, size, etc., but no matter what 
I do, no text appears.

When I run the same code on my Unix R, the strip labels appear no problem.

Does anyone have any suggestions about how to reconfigure my lattice
window?

Thanks
Jason
