Windows GUI package install annoyance

Folks:

A minor (R 2.2.0) Windows package install annoyance, but I can't figure out
how to fix it. If someone could tell me how or point me to the appropriate
docs, I would appreciate it. 

I set my CRAN mirror in my Rprofile.site file. After startup, I get:

getOption('repos')

                          CRAN 
"http:/cran.cnr.berkeley.edu/" 


However, when I then go to the GUI "Packages" menu item and click on
"Install packages..." I get:

utils:::menuInstallPkgs()

Warning: unable to access index for repository
http:/cran.cnr.berkeley.edu/bin/windows/contrib/2.2
Error in install.packages(NULL, .libPaths()[1], dependencies = TRUE, type =
type) : 
        no packages were specified


However, If I now manually set my mirror (through the menu: "Set Cran
mirror" item, which invokes chooseCRANmirror()) , and now check my repos
option, I get again:

getOption('repos')

                          CRAN 
"http://cran.cnr.Berkeley.edu" 


## but now the "install packages.." menu choice works! 
Is there an easy way to avoid having to manually re-specify my CRAN mirror?

My apologies for wasted bandwidth if I have overlooked something obvious,
which I believe is the case.

Many thanks.

Yes: do not omit the second "/" after "http:" in 
"http://cran.cnr.berkeley.edu/" .....
