Drush & Fbconnect on Windows 7
Drush uses a different php.ini than the web server does.  The phpinfo() you are looking at above is from your web server's php.ini.  Run drush status to see the path to the php.ini that Drush is using.  Then, compare the two and copy directives from the web server php.ini, such as the directives that enable the CURL PHP extension and memory_limit, and put them in Drush's cli php.ini.  Then everything should work fine.
