Hi all, I’m getting this odd message and wonder if someone can help please. When I try to reply to a FB message using SE I get this error: “InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index” In details: in SE I go to messages Alt V>messages . I highlight a message, tab to select and enter. When I type a reply and hit reply I get the above error message. What the heck is going on? TIA, Amro
