It drives me a bit crazy that Skritter often has trouble recognizing a right angle stroke. The stroke is héngzhé 横折, i.e. left-starting horizontal then right angle down stroke.
Anyone else have this problem? I can't figure out a way to draw the stroke that will avoid this.
I raised this issue a few years ago, and Nick said he'd look into it, but it's still a problem for me. I have the problem with both the iOS app and the web/Flash version.
This difficulty occurs in many characters. For example 鑰:

Here's a screencast showing my problem:
