I had this problem running Windows 7, but as I posted earlier, it
disappeared I when added an exception to the Windows firewall. After a
recent hard disk crash I installed the latest Anaconda version (1.7.0) as
well, but for some reason I didn't need to tweak the firewall this time.
One issue that might be related (or not) is that I cannot open IPython
notebooks via the launcher: The IPython dashboard uses the program
directory as its working directory and fails because it has no write access
for the autosave files (new in IPython 1.0). The workaround in this case is
to put a link in your working directory and start the IPython notebook from
there.
Cheers,
Christian
