[R-SIG-Mac] new quartz windows show up when R.app in background

[Chabot Denis]

Hi,

I sometimes use Sweave to combine analyses and a large number of  
plots into a document. Executing the Sweave job sometimes take a  
while and I switch to another app and keep working.

Usually my many plots are done with pdf device and all is well. But  
for this particular one, I'm making them with quartz and quartz.save  
to get png files.

However each time R reaches a part of my script where a quartz  
graphic is created, the quartz window comes on top of the application  
I'm using (say Mail) and then goes behind.

I never had the occasion of getting new windows created by a  
background application other than R, so maybe this is absolutely  
normal behavior, but I'm asking in case something can be done to stop  
it: is it absolutely necessary for new quartz windows to pop up  
disturbingly in front of active apps if R is not the active application?

Maybe I could avoid this behavior by not creating a new quartz window  
each time, but my plots are not all of the same size so it is easier  
to start each one in a new window.

Cheers,

Denis
