Hi folks,
after reading FAQ and searching in MIRC-options, i didn´t find out where i can change a value how many textlines are shown in a chan. My MIRC only shows about 30-40 lines per chan. If any new messages appear in a chan, the oldest line is deleted automatically

So i canot scroll back e.g. 10 hours to check what was written in this chan.
MIRC is newest version v6.35
