Unable to reply to replies of tweets
Ok, steps are as follows:
1. Go to Me Tile
2. Click on your current status (next to your picture)
3. Wait for the replies to load.
At this point, you are then unable to reply to any of the replies to that particular tweet. You can copy it, but not reply to it. The text entry box will be starting with @yourusername which will reply to your original tweet, which will disrupt the flow of the conversation.
There should be a way of replying to the replies of your tweet from that screen.
