Forums mIRC Help grey line

"How do I turn off/disable the grey line that marks where I was when I minimise the channel and chat windows?"
please and thank you.
I payed for a copy of mirc yesterday an updated today, but I have this grey line that is drivimg me nuts. I love all the other bits of 6.31 though.
Kind Regards and thank you for all your hard work.
