Web server running at startup

[raffaele]

Hallo
I recently installed a trial of Architect 3 and created a small testing app, which I previewed through an existing webserver (not using Cmd).
Since then, when I call localhost:1841 I find it is already serving that app, and when I try to stop it I get

[ERR] Connection refused

.
When I issue another

sencha web -port 1841 start

every thing runs fine as if there was no webserver already running on that port.
Hence, when launch another more "start" I get the correct

[WRN] Error starting jetty: Address already in use

as expected.
So there is a jetty running at the system startup, using the 1841 port, but it is somehow "transparent" - anyway it prevails to any other jetty instance and doesn't let me run any other Sencha app.
Any idea?
Thanks in advance

Environment:
OSX 10.9.1
Previously installed: Sencha Cmd 3.1.2.342 (uninstalled by the provided uninstaller)
Sencha Architect 3.0.2.1375
Cmd 4.0.2.67

My first question would be, do you ever use Cmd from the Cmd Line (outside of Architect). If so, have you started up a "sencha app watch?"

[raffaele]

Never.

[jminnick]

can you open the help screen in architect and tell us which channel?

I have, is there a way I can undo that it's blocking the port
