[udpsend] strange behavior

[avilleret]

1. open udpsend-help.pd
2. change the connect message to [connect 127.0.0.1 8888( and click it -> [udpsend] reports 1. on outlet, it is connected while nobody is listening on port 8888.
3. open udpreceive-help (with [udpreceive 9997] inside)
4. in udpsend-help.pd, click on [send 0 1 2 3(, nothing is receive, OK
5. now click on [port 8888( on udpsend-help.pd to change port number.
6. in udpsend-help.pd, click again on [send 0 1 2 3(, nothing is received while it's reported to be connected on port 8888

I have to disconnect and connect the [udpsend] again to make it work.

So, if we change the binding port of [udpreceive], the sended messages are not received until reconnection of [udpsend].
