ooh, nice and jiggly - looks to me like an issue with console buffer size (the buffer is too big for the window in which the game is rendered). Try this:
- right-click on the window title bar
- go to Properties>>Font
- decrease the size of the font a bit
- grab the bottom-right corner of the window and enlarge it as much as possible
I'll try to find a way to check for the screen size and automatically adjust the console buffer and font...
