Problem with graphics device in Mac OS X

Hello List,
   I am teaching a basic course where students are encouraged to use R. There are a few students using Mac OS X. As a test we downloaded and installed the latest .dmg file (R-2.6.1.dmg) onto a intel Mac running 10.5.1. A device query yields
"quartz"

But any plot command does not bring up a plot (e.g. plot(), boxplot(), hist()).

I found a thread concerning X11 windows under Mac OS X but I feel these users will most likely be just using the native quartz device.

Invoking a call to quartz() first does not seem to help, e.g.
produces no output and no error message (Nothing happens). A call to dev.cur() seems to indicate a device is active.
quartz
2

but again a plot command produces no figure. Sorry am I not a Mac OS user and I did check the archives but found mostly discussions on X11() under Mac OS X.

For whatever reason, on the Mac, you have to open a new Quartz device window
before making the graphics call.  So, from the menu, pull down under Window
to New Quartz Device Window.  Then all graphics calls go to that (initially
empty) window, and any further calls replace the previous contents of the
window.  This window doesn't print so well, but your students can divert
their output to a pdf easily for really nice plots.

BTW, people were reporting problems with OS 10.5 and R.  These may have been
fixed, but if you have trouble, it's discussed in the archives.

I think you should post this to R-Sig-Mac.
I don't notice any problem at all on my system with the same  
configuration.
