[R-SIG-Mac] strange interaction of quartz() with videoprojector

[Kenneth Knoblauch]

Hi,

The new graphics window defaults in R 2.7.0 are great but I've
noticed a strange phenomenon when I'm using R with my MacBook Pro
connected to a videoprojector.  Under these conditions,
the quartz window that is opened is tiny,
about 1/5 the default size and the line colors are a light
grey (or a light color, at least.  Not 100% sure that it is grey).
As soon as I detach the videoprojector and reset the
display size, everything returns to normal.

The minimal example would be to hook up your portable to
a videoprojector, start R and run

quartz()

Does anyone else see this?

I can get the normal default with

quartz(width = 30, height = 30)

but the text and points are very small.  I can get around this
with cex and col arguments but this is not optimal.  Not great
for teaching.

Thank you for any suggestions.  SessionInfo below.

Ken
