Is it really necessary to Ctrl-C on connect?

Ah… I see the reason, thank you.

If you enter a few characters before you disconnect, when you reconnect do you get the same problem? If I changed the Web IDE to send a space before the Ctrl-C it might magically fix it?

No few chars doesn't fix this. However looking at jsinteractive.c I can't understand why. Looks like jsvIsEmptyString(inputLine) always true… I need to inverstigate deeper.
