Having this code in Remote gives different behaviour in 7.23.

Code:
ctcp ^*:*: { 
  haltdef
}


Execute command:
//.raw privmsg $me : $+ $chr(01) $+ PING $ticks $+ $chr(01)


- mIRC 7.22 and before correctly don't show any data
- mIRC 7.23 however doesn't respect the "^" in combination with halt or haltdef:
