Opening a new window with specific dimensions

hey, i have used the function before where you can have a new window open up from your flash file on release of a button, and have the new window set to certain dimensions and minus the toolbar. I have had to remake my site and lost how i did it and now cannot find a good tutorial for this.

Any chance someone could link me to a few good ones ?

I am using flash mx 04 pro.

Cheers
