Sorry, I know there are at least two discussions of this but I have searched and searched and can't find one.
I am still unable to Chat after Teleport without reloading. Yes, I have migrated to the Group Chat (Greeter). I can enter a comment but it will not post. Saturday morning I returned after a Greet. I had nothing to comment on and believed I was in my Group. After several minutes with no new Greet, I checked "/who" in the Chat only to find that I was NOT listed. So, I typed a comment and it did not appear in the Chat. This was especially strange because I was able to type "/who" and get the list of players but I could not post a comment and had to refresh my browser to make it work.
ETA: BTW, I was "unmuted". WIN 7, FF 6, Flash WIN 10,3,183,10
ETA #2: Happened to me again today, Sunday.
