In the U.S. version of the software (Mac) why do I have to scroll down through 20 media sizes before I can get to 11x17, one of the three most common sizes of media used domestically for printing? Most of the 20 sizes I have to scroll through are either European or Asian or just plain oddball sizes. Why aren't letter, legal and tabloid the first 3 listed? I'm hoping someone can explain Adobes logic to me. Thanks.
