Is there something wrong with v7.22 of mIRC?
I was trying to use many snippets that seems not to work, but I'm starting to think that the problem is with the client itself.
I'm using a clear installation of mIRC!! The only .ini loaded contains exactly the code above.
When I type "!track 208.67.222.222" (without the quotes, of course) nothing happen.
Same problem for all snippets that I must to type something.

Strange think: For remote users it works perfecly!
I've tried this:

on :text:TEST*:#:{
echo IT WORKS!
}

And when somebody type "TEST" I can see "IT WORKS" on the console.

Somebody knows what can be happening?

Thanks you and congratulations to Jethro for all those snippets :-)
