Can flash detect monitor resolution?

Can flash detect monitor res, or any other system resources (processor speed, browser, pop-up blocker, memory, etc.)?? I know there are secutity issues, but i would like to create a detect/launch page for some eLearning courseware. I currently use javascript to do this but would like to use flash.

yup. And here’s what else you can get
