I'm unable to find the location where the options that you indicate are available. Would you kindly provided a detailed explanation regarding the location of these options, so that I'm able to locate them.
I tried using Options from the toolbar menu, and wasn't able to locate Control.
So then I tried the nicklist right click menu, which has a Control section, but while it has the ignore, op, and voice options, as you indicate, it doesn't have protect and it does have kick and ban options.
This was located on a clean installation of mIRC 6.21
