A small section in the options dialog could work too I suppose..
Actions to be performed when Ctrl+Break is hit:
+------------------+
| [ ] /timers off |
| [ ] /remote off |
| [ ] Stop signals |
+------------------+
Why set remote off? i think it would be enough if ctrl-break should stop the running script, if it turn's remote off, then that mean all other scripts you running would be halted. Enough if the script cosing problem halts, so bether if it was a good error check instead.
