[Gambas-user] Really weird socket problem

[nando]

My experience over the years with Gambas and really odd issues
that appears to point to Gambas failing always (ALWAYS!) was that
Gambas did not fail, but something else broke.
Unless you have a hard drive failure, bad cable, etc, your Gambas
is almost certainly working just fine. Something else changed
somewhere else.
Try telneting from a shell to what you want.
Remember, windows update can reset firewalls, add rules
do things and change settings and never ask you.
Look there first.  You'll find windows is probably the issue.
