Did you turn off your modem and router? Wait 5 minutes and turn them back on. I have not seen those errors since I did that.What arrow thingy? I don't see one. I am on desk top. Also noticed my Smilies have vanished since yesterday, as well as that bar that has all the stuff like bold type, different fonts, etc. etc. Sorry I don't know the proper name.
yesterday that Bad handshake thingie popped up, so I took that as an omen to quit and go to bed.
