um...a new install of mirc wont solve your problem. For a start, mirc has a set limit of lines that are allowed to be displayed in ANY window (status, channels, queries, etc). CHANGING the amount of lines to a higher number will give you more lines allowed in any window. The reason it cuts off the first few lines at the top is because its reached that line limit, and will keep deleting the first few lines when new lines are added. If it didn't do this, the amount of text in the window (if left running continously for days on end) would be HUGE, unmanagable and memory retentive. If you want to be able to see what text was in that window before, try using the logging feature in Options, ALL data from that particular window will STILL be there in a text file.
