mIRC Version: 6.31

I have a few month old log file that I want to view in a custom mirc @window.

The log file is:
12,509 KB
196,269 lines

I try to scroll with the (tiny) scrollbar from top to bottom, and when I get almost 1/3rd of the way through, the scrollbar goes back to the top, and I can't get past that point down the scroll bar. I don't get this issue with any files except really huge files. This doesn't happen when I view the same file with notepad.

I used:

/window @test
/loadbuf @test logs/really.long.file.log

To reproduce:

Try loading any really large log file into a custom window, for example your status log file.

Thanks.
