It does insert "/" and then press enter.
Yeah, it does that. I wasn't thinking about that when I replied.

In any case, I think it *should* show the last line in the active editbox regardless where mIRC's running that command. I don't think mIRC is handling that second editbox correctly in this case. I think the / should be done in the active editbox as well. It doesn't make sense to have it working in an inactive editbox on the active window instead of the active editbox in the active window for the original example, imo.
