Sorry, but you are still borked. OpenThread() takes a thread ID, but as I mentioned above, thread IDs are only unique within their process. If you try to call it with thread ID == 2 (say), it will attempt to open thread 2 of the current process, in this case, perl.exe (which may or may not exist), not the process you are attempting to change.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
