it may depend on "how" the computer has no internet connection. Normally
if there is no connection at all, it will fail immediately. I ran into a
problem (with Revonline) that if the computer has a working connection
to a router or other connecting machine, then it can fail.
See Bugzilla 2117 for some more info and a hint of a possible workaround
I think you could also use a non-blocking URL request, if that was easier.
