DNS caching(?) page-hangup issues and Opera 10.X

I'm using the latest X64 build (which I guess is now 10.60), but for a
long time now Opera always hangs up resolving hostnames every time I
switch networks on my laptop.

It's apparently trying to cache the previous DNS server; eventually it
must be uncaching what it knows, as after a while I don't get hung up
on "looking up hostname _____" (and since the page-loading timeout is
less than the DNS resolution timeout, many times pages just stop loading
over DNS issues).

Is there any setting I can use to either flush DNS or stop it from
caching DNS? I'd much rather prefer to use my local caching server on
127.1 anyway.

Thanks,

	-Kenny
