/clipboard command not reliable? - mIRC Discussion Forums

With the following code, mIRC apparently misses one or more of the /clipboard commands

Code:

alias cbbug {
  clipboard
  var %string = A B C D E F G H I J K L M N O P Q R S T, %n = 1
  while ($gettok(%string,%n,32)) {
    clipboard -a $v1
    inc %n
  }
  var %copy = $cb
  echo -a clipboard: $len(%copy) $qt($cb(0).len) of $numtok(%string,32) chars:
  echo -a clipboard: $cb
  clipboard
}

; not required - just for convenience
alias cbtest {
  .timer -m 10 50 cbbug
}

Edit:
v7.19, XP mce; and it's not related to the -a switch:

Code:

alias cbbug2 {
  var %string = A B C D E F G H I J K L M N O P Q R S T, %n = 1, %copy
  while ($gettok(%string,%n,32)) {
    clipboard $v1
    var %copy = %copy $+ $cb
    inc %n
  }
  echo -a clipboard: $len(%copy) of $numtok(%string,32) chars: %copy
}

Tested both on 7.19 Windows 7 and always get 20/20 without error.

Same here, win7 and mIRC 7.19, can't reproduce it.
Tried on a clean mIRC?

I did (restarted the sys as well). I'll start checking with older versions now.

Use -s to display what the variables are set to at the time they are set and see if that helps you find the problem.

Do you have any other software running that could be monitoring/modifying the clipboard?

Several blind alleys later, I finally managed to identify the cause of the problem: a java applet with the ability to monitor the clipboard (to catch-and-process a set of specific urls on occasion), burried in my system startup routine.
Even though the actual cb monitoring option of the app was disabled for the time being, it apparantly kept reading the cb and thus, somehow, interfered with the rapid, successive cb-access attempts of mIRC.

Thanks to all who looked into the issue; sorry for the bother!
