[Manifold-l] download problems - still

Tue Oct 17 03:08:04 CDT 2006

Another contribution. We've used Firefox in unaltered configuration and have
had smooth and trouble-free downloads. We have a basic broadband connection
from an ISP (IInet) which uses the old Telstra copper infrastructure - we
piggy back a VOIP and fax off the same landline; we are physically located
in Tasmania - it's a long way from Manifold's servers. Maybe we're just
enjoying good luck, so here's hoping some can trickle your way too!

Cheers,
