Haven't had that problem, but a problem I have had recently is that it won't send a pic. Otherwise it's great for text chats, been a long time since I used video, wasn't too good then, but it could have been my connection.
No issues for me other than nobody to chat with today.
AS for the not sending pictures, that is probably a setting for the other person. I have a contact that won't allow pictures because of the computer she's on. Others work just fine.
