I've always had trouble remembering the 3rd and 4th strokes of this character (left or right?), and I've finally figured out why... this character is inconsistently laid out in various dictionaries, books, websites, etc. In fact, when I type "guo" in Google Pinyin, the popup for choosing characters shows strokes 3/4 on the left, but when I choose the character and it appears typed, the strokes are on the right. Incidentally, Skritter's 過 is left-aligned.
If it's hard to understand my meaning, compare the various characters on this Wiktionary page: http://en.wiktionary.org/wiki/%E9%81%8E including the animated character.
So, what I'm wondering is, when handwriting this character, is there a more correct version? Or, like with the printed character, is there really no difference?
