More questions on Key

I am working on an image box what will resize itself and move with keyboard input

e.g
UP, DOWN, RIGHT, LEFT => move

SHIFT+UP, SHIFT+DOWN, SHIFT+RIGHT, SHIFT+LEFT => move faster

CTRL+UP, CTRL+DOWN, CTRL+RIGHT, CTRL+LEFT => Resize

CTRL+SHIFT+UP, CTRL+SHIFT+DOWN, CTRL+SHIFT+RIGHT, CTRL+SHIFT+LEFT => Resize Faster

the one direction combos work (right left, up down) and in most cases the angles work too (right/down, right/up,left/down,left/up) with the exception of CTRL+LEFT+UP & CTRL+SHIFT+LEFT+UP [though the left+up and SHIFT+left+up work great!] on top of that, when running the movie outside of the dev Environment, most of the CTRL+ actions work sparratically…

  1. does anyone know why CTRL+[SHIFT]+LEFT+UP wouldn’t work?
  2. does anyone know why CTRL in general would work badly in a standalone SWF?

winXp, flash8 player um, disable keyboard shortcuts checked.
