I tried with the R.app GUI you suggested, but nothing has changed.

I try to answer to your questions: I always work directly in the R console,
typing the commands and then pressing the Enter key. I never use scripts.
Now I tried to write a script using the dataset persproject. The script was
as follows:

attach(persproject)
library(Rcmdr)
plotMeans(Recall,Dosage)

When I selected 'Execute' R went down and remained like frozen. I had to
force quit. If instead I type directly in the R console I obtain the
following:

> attach(persproject)
> library(Rcmdr)
Carico il pacchetto richiesto: car
Carico il pacchetto richiesto: MASS
Carico il pacchetto richiesto: nnet
Loading Tcl/Tk interface ...
> plotMeans(

and here, when I type '(', the *** caught segfault*** error appears.
Moreover I tried some other function of the Rcmdr package, and all of them
produce the same error. It always appears when I open the parenthesis '('.
I specify that some days ago I uninstalled the package Rcmdr and try to
reinstall it, downloading it from a different CRAN mirror; but nothing has
changed.
