I have the same problem... very small problem, but a problem nonetheless. I thought it was just a standard http limit (as such) that was perhaps saved in the registry of your PC?? No idea on how to change it though.

I haven't bothered trying to fix it, but if you do find a fix, let me know :-)

----edit-----

Just taken a quick look on Google. Does appear to be a standard setting within browsers.

Not tested!!!! But with Firefox, do this:

In the Address Bar, type - about:config

Do a search for: network.http.max-persistent-connections-per-server
DEFAULT SETTING IS "6" - Coincidence yes??
Try changing that to 10? 15? 20? I think the max is 255

Restart Firefox, and let us know.

I've just tested this myself, as I'm now at home... This worked for me. I was able to have 10 active connections to my Rapidleech with no problems. I hope this solves the problem for you aswell.
