I am not exactly sure what the problem is and do not have time to
investigate at this exact moment, but until I get a chance to look at
it might I suggest that you try


at the command prompt when Rcmdr shuts down (and will not return);  it
is the basic way to restart Rcmdr when it goes away.

I will have to boot into Windows later this evening to investigate,
but in the meantime you may want to post your sessionInfo().  I have
run RcmdrPlugin.IPSUR on R-2.10.1, Windows XP, as recently as
yesterday during class without any problems.

Gotta go for now.
