Hi James,

It seems to be that way. The connection I was browsing the page through 
was being port-forwarded through a PIX firewall. I've gone through the 
VPN (an alternative route that doesn't hit the firewall) and haven't run 
into a timeout issue so far.

Any idea if there's a fix in the works, or if there is anything that I 
can do? At the very least, it's good to know that the issue is known. 
Thanks for the insight!
