Thanks in advance. When I tried to login this morning, I had difficulty. Then I checked my firewall log, I found there was no connection made to IB gw*lc servers. But there was a connection made to www.interactivebrokers.ch My question is, is this site really your server? I am not sure whether it is the standalone tws or my browser made it. BTW, after I closed my browser, the login problem (in standalone tws) was gone. Strange. I was just a little paranoid and want to ask to make sure. Thanks.
