问题 Im making a game in FlashBuilder where the player controls a movieclip (_character) around the stage with the arrows or WASD.

While testing Ive noticed that if I hold a direction key, then switch to another AND the MovieClip is travelling past a gap in the boxes, the movieclip will jump a few pixels in the previous pressed direction, then back down again quickly.

问题 Is ENTER_FRAME always received, even if another process occupies the CPU, OR the listener might miss one or more ENTER_FRAME events -then receive several of those events delayed in a batch as usually happens in Windows?

While moving the characters body and head should be still, with the legs moving. Example below _character Right
