A Quickwin window is a bitmap that emulates a terminal - sort of. If the bitmap is made large enough you can automatically reposition the viewed region. CVF had a sample that showed this - I'll see if I can reconstruct it next week. I will caution you that the larger you make the bitmap (so it can hold more lines), the more memory it takes and there are upper limits.
You may want to consider calling AllocConsole and writing the monitoring text to a console window instead. It will use less resources and you'll get the automatic scrolling you want.
