And, just for the record--the Finder is what is running when you turn the computer on. I too am barely computer literate, and had to have this explained to me also! Think of it in connection with finding all the files you misplace (click on 'File' up in the header, it's usually at the bottom of the pull-down list). And you will misplace Poser stuff, because there's so much of it ;) (Oh---and when you click on the app to change memory, don't do what I did and click on the folder that contains the app. You have to go into the folder and find the program itself and select that!)
