Cran task views seems to be a "once-per-session" process -- the first
attempt to access views in a (RGui for Windows) session works, but
subsequent attempts fail. There is a noticeably long pause before
the failing call returns.
Example session with two calls to "available.views" follows, but similar
effects have been observed with two calls to "install.views" and even
a call to "available.views" followed by a call to "install.views".

One comment - taken from the FAQ - in advance:
Bug reports on contributed packages should be sent first to the package
maintainer, and only submitted to the R-bugs repository by package
maintainers, mentioning the package in the subject line.
In this case, posting to R-devel (but not R-bugs) and Cc to me (as the
maintainer of ctv) would also have been ok.
As for your problem: On my Linux machine, the code
library("ctv")
x <- available.views(repos = "http://CRAN.uk.R-project.org")
y <- available.views(repos = "http://CRAN.uk.R-project.org")
runs without any problem, x and y are also identical afterwards. As I
haven't got a Windows XP machine, could someone on the list please run the
code above and confirm (or disconfirm) that the second call takes longer
and finally finds no views.
thx in advance,
Z

It works correctly on my XP machine.
I don't find http://CRAN.uk.R-project.org a particularly reliable source
(and it is like me in .ac.uk), so wonder if this might have been a
networking or mirror glitch. I would have tried another mirror (the
London one is more reliable for me) long before reporting a problem.
