Today I have put a new version of RAqua installer package on my page 

It is sync-ed with today's r-devel (11 GMT)

navigation API allows you for that by specifiing window modality 
opportunely. Have a look inside NavSample code in the Carbon SDK 1.6 
from apple. THe "modern.c" file explains how to do these sort of stuff.
Sheet window are a problem as the dialog does not exit after a user 
selection (just like any ohter dialog!!!) but just after opening the 
dialog. You have to write some dedicated event loop code. I've avoided 
sheets for this reason.
