function is persistent on any following code that does not have

Upload code.
<br>imp.configure("First Program", [], []);<br>"Hello, World!");<br>

Run the code.

The node labels and message changes correctly.

Upload new code:
<br>local ledState = 0;<br>function blink()<br>{<br>&nbsp;&nbsp;&nbsp; ledState = ledState?0:1;<br>&nbsp;&nbsp;&nbsp; hardware.pin9.write(ledState);<br>&nbsp;&nbsp;&nbsp; imp.wakeup(0.1, blink);<br>}<br>hardware.pin9.configure(DIGITAL_OUT_OD_PULLUP);<br>imp.configure("Blink-O-Matic", [], []);<br>blink();<br>

Note that this new code does not contain and thus the node keeps the same message from the previous code.

Thanks reefangel.  Unfortunately, is persistent, for now.  We’re planning on fixing this in the near future.

Is it possible to have an issue tracking system?
Something like github has?
I personally use github for my arduino libraries and works good for me:

We’re working on this. Github is one of the possibilities we’re looking at.  In the meantime, please continue to post bugs on the forum and, we’ll log them into our internal bug tracking system.
