[Rd] help.search() in html?

[hkawakat at gmail.com]

Hi,

I have options(help_type="html") in my .Rprofile and when I type
?foo, the man page appears as a new tab in my web browser (which is
already running). Fine. However, when I type ??foo, rather than the
results appearing in a new tab, a new instance of the web browser is
spawned with the default homepage displayed. Same with
help.search("foo"). Am I the only one seeing this? Is there some
setting/option that I am missing?
(At the moment, I bring up a man page via ?foo and then manually
follow the <Index> link at the bottom of the page to go up to the
search engine page.) R --vanilla shows the results of ??foo in the
terminal window as expected.

I am running
