Hey everyone,

have a question. Is it possible to detect whether the user used or is using ctrl+scroll to enlarge the screen? I was looking at an example of a mouse avoiding game, which could easily be cheated on using ctrl+scroll, so that the passages were larger etc.

Is there any way to detect this inside Flash, and perhaps prevent it?
