I was debugging and logging messages in my app while using your debugger on my second monitor and I noticed the Debug output window only repaints when you either focus the cdbg64 application window or when you move the mouse over it (windows repaint).
This is pretty counter-intuitive when you are testing within your own application window and don't see the output straight away in the debugger window (on your second monitor for example).
I love the debugger so far and this is a minor thing, but I just wanted to let you know :D
