Weird behaviour with more than two participants.

[neuhaus]

When I click on receive and then use the key with two other clients and click "send" there:

• the two clients that press send cannot see each other's text
• the receive client will receive the entire thing what the last client that sent something sent.
• When the receive client receives something and then also types in the text area only one of the senders sees the response.

Sendstr currently is designed for 1-to-1 communication but it shouldn't be too much work to support 1-to-many. I'll work on this next. Thanks for submitting an issue!
