Can't seem to size my popups correctly. I tried taking the layout hight and width (in pixels) and I get scroll bars. I then oplay the guessing game (waste of time) and if I make the popup too big, you can see where my layout backgorund ends (looks awful). I tried pressing Command+A and taking the RIGHT position value from Insepector, but I still get scrollbars because my layout background is wider than where the last object is placed. What's the trick to this?
