I'm on a Mac Mini 2011 with VirtualBox installed. I have Windows 7 running as a Guest OS.
My question: How do I "trap" my mouse pointer within Windows? In other words, I don't want my mouse to move outside to the Host OS. Ideally, I would be able to press the Host key to "untrap" my mouse.
The purpose: I'm playing Warcraft 3 in the Guest OS and I can't scroll the screen since the mouse keeps jumping to the Host OS instead of scrolling the screen. This happens even in full-screen mode.
